4 Types of Fungi that benefit your plant roots

Recently, I researched how to make a better soil mix for my plants and made a note of the benefits of these fungi that can be mixed into the soil to improve plant growth. Rhizobia These are bacteria that can form a symbiotic relationship with certain plants, such as legumes, in which the bacteria fix nitrogen from the air and make it available to the plant in exchange for carbohydrates from the…

STRATEGIES FOR IMPROVING NODULATION AND NITROGEN FIXATION OF LEGUMINOUS CROPS TO ENHANCE PRODUCTION IN SMALLHOLDER FARMING SYSTEMS |  Journal of Global Agriculture and Ecology

Leguminous crops play a unique function in biological nitrogen fixation, which allows them to fix atmospheric nitrogen in the soil. In the presence of nitrogenase, biological nitrogen fixation is a natural way of converting atmospheric nitrogen (N2) to ammonia in a form that plants can use. Farmers in Sub-Saharan Africa face an issue with low agricultural productivity. Low yields in leguminous crops are a result of diminishing soil fertility, reduced N2-fixation, soil acidity, overcultivation, and poor soil management methods, all of which cause soils to be nitrogen and phosphorus deficient, rendering them prone to erosion and resulting in land degradation. It has been found that organic matter treatment elevated soil pH from 5.0 to 6.5 after 90 days. The majority of farmers in Sub-Saharan Africa cannot afford the high prices of mineral fertiliser, so much of it is imported, putting a strain on foreign exchange. As a result, farmers are recommended to intercrop with legumes or undertake crop rotation to assist enhance soil nitrogen levels and thus production. This review paper aims to disclose techniques to improve legume nodulation and nitrogen fixation in smallholder farming systems in order to boost production.

Protecting mungbean rhizobia

by Paul McIntosh, Pulse Australia

Effective nodulation of mungbeans can fix about 60 to 70 kgN/ha, sufficient to grow a 1 t/ha crop. If the rhizobial inoculant is not applied or if the bacteria are exposed to high temperatures and die, this nitrogen will need to come from residual N reserves in the soil or from a pre-plant application of urea or Big N.

The survival of Rhizobia bacteria is very low if the inoculant product is exposed directly to the hot sun and temperatures above 33–35 degrees C. It only takes a few hours of exposure to the sun and high temperatures on the back of a paddock truck or in seed bins ready for planting for high levels of mortality to occur, rendering the inoculation process ineffective.

Even if you have grown mungbeans in the paddock in the past, you simply rely on a large enough population of the mungbean strain (Group I) of Rhizobia being present in the soil. Water injection into the seeding furrow using cool water of neutral pH is the best application method to promote rhizobial survival and efficacy.

Avoid mixing inoculant with liquid fertilisers. Even though liquid fertilisers are a very desirable nutrient application option, rhizobia are very sensitive to pH and direct contact with elements such as copper and zinc.

Some farmers are now adopting the practice of applying nitrogen prior to planting mungbeans to make their planting operation very smooth and staff efficient. Keep in mind that these nitrogen applications should be pre-plant and not just at planting because a wetting front is required to push this relatively mobile nitrogen deeper into the soil profile, where the roots of the young mungbean plants are developing. There is no sense applying nitrogen into dry-ish topsoil while the mungbean roots develop in a good moisture zone lower in the profile. This is particularly important in fast growing mungbean crops where there is very little time to fix a nutrient deficiency.

If you plan to use applied nitrogen rather than (or as well as) fixed nitrogen to meet the mungbean crop’s needs, a nutrient analysis of the soil profile well in advance of planting will help avoid having a sad, nitrogen-deprived mungbean crop three to four weeks after planting. There is no advantage in applying a high rate of nitrogen fertiliser and also applying inoculant, because rhizobia will only fix nitrogen effectively if the soil nitrogen levels are low. However, if your applied nitrogen remains positioned in the drier top soil layer, then seed inoculation may still be very effective.

More about rhizobia survival

Rhizobium bacteria are able to live freely in the soil without a host for a time but generally only when soil conditions, especially pH, are favourable to their survival. Rhizobia and their host legume tend to have similar pH tolerance. Inoculation is generally recommended for pulses (other than lupins) grown on soils with pH below 6 (CaCl2) or below 6.5 (in water).

In higher pH soils, rhizobia associated with all pulse crops can survive for several months without a host plant. Many growers choose to use inoculant every time they grow mungbeans to be sure that the crop will nodulate effectively and fix atmospheric nitrogen to at least meet its own needs.

High biomass crops and narrow row spacing promote increased nitrogen production through fixation, contributing more to the N-budget of the rotation.
