5 Early Spring Veggies You Can Plant Now

Julia W. Soil biology is important for keeping agricultural systems healthy and productive. Living soil is complex. It includes creatures that cannot be seen with the naked eye, such as bacteria, fungi, actinomycetes, protozoa and nematodes, as well as creatures such as insects and earthworms. This community of organisms is bound together in a food web that affects the soil's chemical and physical properties.

We care about these properties because they also affect plant growth and health. Practices such as adding manures or composts to soil, planting cover crops and rotating crops are all aimed at rebuilding and maintaining soil organic matter, recycling and retaining nutrients, and decreasing soil diseases. These practices are usually associated with increased microbial biomass and increased soil organism diversity.

A healthy soil can contain billions of bacteria, fungi and other microorganisms in one teaspoon. Depending on soil conditions, the populations of these different microorganisms rise and fall.

Some microbial populations increase quickly when fresh cover crops or other plant residues are added to the soil. For example, some microbes are able to use the readily available sources of carbon from fresh plant residues like humans use carbohydrates.

These microbes decrease as the carbon sources are used up, causing other microbes that break down the less available sources of carbon like cellulose and lignin to increase. The point is that there are many native microorganisms in the soil that respond quickly when conditions are favorable for their growth. As we continue to recognize that soil biology plays an important part in crop production, interest in soil inoculants continues to grow. Inoculants are used for a variety of reasons.

In some cases, we add soil organisms that have a known beneficial effect. For example, some bacteria, like rhizobia, form a symbiotic relationship with certain host plants, like legumes. A symbiotic relationship is one that is mutually beneficial. In return for the plant feeding it carbon from photosynthesis and giving it a home, the bacteria can "fix" atmospheric nitrogen into a form that the plant can use.

Some fungi, like mycorrhizae, can also form a symbiotic relationship with plants, scavenging phosphorus and other nutrients for the plant to use. Some bacteria and fungi do not form a symbiotic relationship with plants, but, when added to soil, can promote plant growth, suppress plant pathogens or both.

The easiest way to think about soil inoculants is to divide them according to their mode of action: biofertilizers or plant growth promoters , biopesticides and plant resistance stimulants.

Biofertilizers contain live microorganisms that, when applied to the seed, plant or soil, inhabit the area around the roots rhizosphere or live in the roots. These microorganisms promote plant growth by increasing the supply or availability of nutrients, by stimulating root growth or by aiding other beneficial symbiotic relationships.

Biofertilizers are also called plant growth promoters. Legumes such as clover, peas and beans have root-colonizing rhizobacteria that can increase the availability of nitrogen to the plant by fixing nitrogen from the atmosphere.

Each legume has a specific rhizobacteria that works best with that plant. Inoculating the legume seed with the correct bacteria ensures the legume will maximize nitrogen availability if nitrogen in the soil is low This is particularly important if you have not planted the legume species before, because the correct bacteria may not be present in the soil. There are also free-living, nitrogen-fixing bacteria that can supply nitrogen to cereal plants such as wheat and corn.

They live in the area right around the root the rhizosphere. In general, nitrogen fixation with both the symbiotic and free-living nitrogen fixers is higher in nitrogen-poor soils. In many soils, nutrients such as phosphorus, potassium and iron are present in large amounts but in forms that plants cannot use.

Many bacteria and fungi are able to make these nutrients available to plants by secreting organic acids or other chemicals siderophores to dissolve the minerals.

Mycorrhizal fungi that live in plant roots are well known for their ability to provide phosphorus to plants. Just like the situation with nitrogen fixers, mycorrhizal fungi are most effective when available phosphorus in the soil is low.

When there are adequate nutrients available, plants do not seem to want to exchange their hard-earned products of photosynthesis for more nutrients. Some bacteria and fungi produce plant growth hormones that can increase root growth specifically and plant growth in general. Increased root growth helps the plant utilize a larger volume of soil for nutrients and water and can help the plant to "outgrow" pathogen attacks. For example, fungi are known to produce gibberellins that are important for seed germination and cell growth, and some bacteria can reduce the amount of ethylene, which is a hormone that plants produce under stress.

There are many examples of soils that are naturally suppressive to plant pests. Suppressive soils are the result of interactions between certain microorganisms and pest organisms. Many of the most common soil inoculants are formulated with these suppressive microorganisms and are used as biopesticides or biocontrol products. Most biopesticide organisms work by either producing a substance that inhibits or kills the pest antagonism or by reducing the availability of food or shelter for the pathogen competition.

The most widely used biopesticide is Bacillus thuringiensis, which produces a toxin that kills soil grubs and nematodes. Specific strains of Bacillus subtilis are widely used as a fungicide. This bacterium colonizes plant roots, competing with fungi for that niche, and prevents the rapid growth of fungal pathogens. Protozoa and nematodes that eat bacteria are also thought to play an important role in controlling pathogens predation.

As with any ecosystem, both competition and predation tend to keep populations in balance. In addition to acting as a direct inhibitor of plant pathogens, some fungi and bacteria stimulate the plant to activate its own defense mechanisms. This is called induced systemic resistance.

In response to chemical signals from the microorganisms, plants may change physiological responses so that there are fewer symptoms of the pathogen. This may include strengthening its cell wall to resist infection, or releasing antibiotics such as terpenes that reduce pathogen attack. The chemical signals that pass back and forth from microorganisms to plants are specific; consequently, microorganisms and the chemical that may cause induced systemic resistance in one plant species may not work in another.

While there are examples of soil inoculants that successfully improve plant growth and crop yields, their use is still in its infancy. The success of a particular inoculant will depend on the plant species and cultivar. Soil type, soil moisture and temperature conditions, as well as the number of pathogens present in the soil around the plant will also affect how successful the inoculants might be.

Finally, because inoculants contain living organisms, how the inoculants were prepared and applied can affect the outcome. Microbiologists think that the success of an introduced microorganism may be more linked to its ability to reproduce and establish populations in a particular niche around the plant root zone than to the numbers of the inoculant microorganisms applied. Introduced microorganisms must compete with those already in the soil and survive predation from native protozoa and nematodes.

They must find the proper food source and environmental conditions to survive. Introduced microorganisms can be stressed by fluctuating soil water conditions, use of fertilizers or agrochemicals both organic and conventional and soil disturbance such as cultivation.

Because of all these effects, introduced microorganisms may not persist for very long in the soil; thus, the beneficial effects of an inoculant seen in the field are often less than those seen under laboratory or greenhouse conditions.

There are also instances where an application of one type of bacteria or fungus will have beneficial effects while co-application of several do not show similar effects. In general, field trials of inoculants that claim to be plant growth promoters or plant resistance stimulants have mixed results.

For example, data on cotton and sorghum trials over several years in Texas showed no difference in yields with two different "soil activator" products. Another study saw no difference in forages, peanuts, rice, soybeans and tomatoes. Other studies in Alabama have shown several strains of Bacillus spp. Inoculants are formulated and sold as powders, granules or liquids. Inert materials such as peat moss are often used as a carrier to keep the organisms alive and aid in application. There are several methods for applying soil inoculants.

These include coating seeds or seedlings or applying directly to the soil. Direct soil applications are made at the plant base near the plant roots. Different formulations require different application methods.

The manufacturer's recommendations should be followed to have the best chance of success. You should not add any additional products to the inoculants before application, especially those that might have properties that can kill bacteria or fungi.

Shelf life can also be an issue. Because the formulations contain living organisms, they should be kept in a cool place preferably the refrigerator and, once mixed up, used as quickly as possible. Leaving inoculants in the car, on the dashboard of a pickup truck, or outside exposed to the sun, heat or very cold temperatures can kill some of the organisms and reduce their effectiveness.

In Georgia, they must also be approved by the Georgia Department of Agriculture. The Department of Agriculture requires testing to show inoculants are not likely to harm plants and evidence that claims on the label are true. However, users should know that this is not a guarantee that the inoculants will perform as claimed.

Before purchasing, farmers should ask themselves about product claims. The old adage, "If it sounds too good to be true, it probably is," still applies. Ask yourself several questions:. As with any agricultural product, the user should pay attention to basic safety precautions and follow the label instructions. Although the inoculants are not human pathogens and manufacturers are required to take precautions to prevent contamination with other microorganisms, users should take common sense precautions.

These include not breathing sprays, not exposing skin to the inoculant mixture and washing hands after use. Some bacteria that have beneficial effects in the soil can infect people with compromised immune systems. The use of soil inoculants has promise for use in agricultural systems for improving nutrient status, reducing plant diseases and pests, and improving yields.

However, management practices such as rotating crops, growing cover crops and adding organic fertilizers and soil amendments provide similar benefits.

All of these practices affect the numbers and diversity of the microorganisms in the soil. The complexity of the soil and agricultural production systems makes it difficult to predict whether soil inoculants will perform as expected.

Without proper soil conditions, laboratory-raised inoculants often have a difficult time competing with native microorganism populations. Soil Biology Primer. Available online at soils. Inoculation of Legume Forage Seed. Available online at www. Available online at lubbock.

Soil Inoculants

I purchased some bush beans and the package recommends I treat the seeds with a "garden inoculant. These strains of naturally occurring soil bacteria enable plants in the legume family to suck nitrogen—the primary food plants need for growth—right out of the air. Community Gardener Phil Williams in Augusta, Georgia recently sent me an excellent article from the University of Florida's Extension Service explaining that an astounding 35 tons! That's a lot of plant food just waiting to be tapped, and the plants didn't wait for us to do the tapping!

Those of you who have been receiving these newsletters for some time know that many of them have dealt with big general issues relating to agricultural growing methods. Such topics have included the depletion of crop soils by overuse of chemical fertilizers, increasing problems with soil compaction and salt buildups, fertilizer runoff into streams and underground drinking water, the relative absence of research funding to explore biological alternatives, and whether current soil chemistry practices are sustainable.

Seedling Inoculant

Rain, rain go away. Weather is a key factor in achieving big soybean yields, but it is not the only factor. Variety selection, proper rotation, fertility, field management and inoculation are all important. So why do some farmers feel inoculation is optional? Understanding what inoculants are, how they work, and why they matter will get more growers consistently applying them and reaping the rewards. An inoculant is a strain of bacteria rhizobium that initiates nodulation for soybeans, a critical process for survival. Like any good partnership, the interaction of plant and nodule is based on mutual need and benefit. The most common formulation of inoculant is a liquid that is applied to the seed just prior to planting, but there are also peat and granular options, and often some combination of the three is recommended.

Garden Inoculant. A growing medium that can be added to your garden, in particular for peas and beans. It contains Rhizobium bacteria which improves soil.

However, it is not in a form that plants can use. Legumes are plants such as alfalfa, peas, beans, clover, vetch, and their relatives including mesquite and palo verde trees. Legumes help convert nitrogen gas into plant-available nitrogen. In reality, the legumes cannot convert nitrogen from the air without help. They need the assistance of Rhizobium bacteria which live in small tumor like structures on the legume roots called nodules. Rhizobium bacteria can convert nitrogen gas from the air in the soil and transform it into ammonium NH4 , which can be used by the plant.

A garden inoculant is really just anything we use to bring beneficial microbes into our gardens. These microbes are often deficient for various reasons, but if we can get more of them back in there, they:. Before we get into products that you can purchase to bring into the garden that are microbial inoculants I wanted to talk briefly about how we can culture our own micro-organisms. Or if you went also to a, like a pond — a marshy area- that would be a different set of microbes, too and you can bring that to your compost pile or just kind of spread it on your garden. Whereas this is just mainly the lactobacillus.

Biological seed inoculation

For each vegetable you plan to grow in your garden, you will have to decide whether to start it from seed, from transplants, or from plant parts. The main advantage in starting directly from seeds is that you have a wider selection of varieties and sources to choose from compared to buying transplants at a garden center. Furthermore, not all vegetables do well when transplanted, and most vegetables can be grown from seed sown directly in a garden row. This publication provides considerations and best practices for selecting and planting seeds in home and community gardens and is one of many EDIS publications for gardeners in Florida.
