Legumes thrive in soils rich in microbial diversity, balanced cations and ameliorated to neutral pH. A biology-first approach encourages effective nodulation and nitrogen fixation. Pre-sowing compost and lime applications enhance biological diversity and mineral balance. Legumes much prefer organic P compared to inorganic P, as they have a greater capacity to extract P from organic sources.
Seed dressing is critical for rhizobium inoculation to promote nitrogen production. This can be further enhanced if Mo and Co are Essential cofactors for the enzyme nitrate reductase, which converts nitrate to ammonium, the first step in protein synthesis. Co forms part of vitamin B₁₂ (cobalamin), which is crucial in microbial and plant nitrogen conversion pathways.
Worm Granule 531 works well on its own with early-sown crops, or at very low rates of 10-20kg/ha for late-planted crops.
Throughout the season, targeted foliar nutrition guided by DSA ensures optimal trace mineral availability, reducing fungal disease and supporting pod set, seed fill, and grain quality. Key nutrients of focus are
Early vegetative stage
Foliar Mn, Fe, Zn, and Mg to support chlorophyll and nitrogen metabolism.
Pre-flowering
Foliar B, Ca, and K to enhance flowering, pod set, and translocation of sugars.
Grain fill
Potassium, phosphorus, and trace elements to maintain canopy health and protein synthesis.
Cobalt + Mo foliar
At mid-season extends nitrogenase activity and maintains green leaf area longer
