Foliar feeding of soybean in the second half of the growing season
Pod filling, and therefore soybean grain yield, depends on how fully the flowers are pollinated. That is why feeding plants with boron is recommended at the start of budding. Depending on plant condition and weather, we suggest using ECOLINE Boron (Opti) 1.5–2.0 l/ha. This fertilizer contains molybdenum and zinc, which soybean also needs in this growth phase.
June weather conditions are often unfavorable for the crop, with moisture shortage and high temperatures that can cause stress and pod abortion. For feeding plants in this period ECOORGANIC recommends the special fertilizer GROS Quicelium at 0.5–1.0 l/ha. This fertilizer contains a full set of microelements and a balanced set and optimal ratio of phytohormones and amino acids. Thanks to this combination the effect of stress factors on the plant is softened, which helps preserve pods and their full development and, accordingly, raises yield.
On areas damaged by spider mites, it is advisable to apply ECOLINE Magnesium (Chelates) at 1.5–2.0 l/ha or GROS Amino-Mg 1.0–1.5 l/ha together with the acaricide to stimulate chlorophyll recovery and intensify photosynthesis.
During grain formation in the pods, plants need increased nitrogen nutrition and a balanced supply of other macro- and microelements. Therefore we suggest foliar feeding with a 5–6% urea solution combined with ECOLINE Legume (Chelates) at 1.5–2.0 l/ha.
Deficiency of other microelements, in particular iron, may also appear. Symptoms of its shortage show on soybean leaves as interveinal chlorosis. This is the result of a complex disturbance of plant development on soils with an alkaline reaction and/or a high concentration of salts in the soil solution. Chlorosis can be intensified on over-compacted, waterlogged soil and during cold spells. To eliminate the deficiency of this microelement we recommend foliar feeding with ECOLINE Iron (Chelate) 0.5–1.0 l/ha at the start of pod formation.
