“…Before applying a Mn fertilizer, it is important to determine whether sample soils or plants need this element. As suggested by Lacerda et al (2017), the most important aspect when applying micronutrients in the soil, topdressing or seed furrow, foliar or seed treatment, is the application time and dosage of micronutrients to provide the nutrients in adequate amounts the plant requires. In many areas of the world Mn as foliar application is recommended in calcareous soils.…”

Manganese (Mn) as an essential plant micronutrient affects plant development, when at deficient or toxic levels. Manganese is used in several biological processes as an important contributor in plant growth and development. Manganese uptake depends on forms of Mn in soil solution, crop characteristics including growth rate, and ineteractions with other environmental factors. Its distribution in soils and requirement for crops vary from location to location, depending on soil type and reactions. Despite the metabolic roles of Mn in different plant cell compartments, the importance of Mn requirement in plants, distribution in soils and application to crops has been understated. As a micronutrient, judicious Mn management requires to critically evaluating its concentration in soils, biochemical functions, critical levels, soil availability and interactions with other nutrient elements is essential. This review has critically analysed the existing body of knowledge on Mn distribution in soils, dynamics, functions and management towards better crop production and safe environment. Environ. Sci. & Natural Resources, 12(1&2): 225-242, 2019

“…Sutradhar et al (2017) and Calonego et al (2010) also reported increased leaf B content of 24% and 39%, respectively, and did not observe any increase in soybean yield. Lacerda et al (2017) attributed the unresponsiveness of the soybean crop to B fertilization reported by Calonego et al (2010) to high soil B availability; contents were 0.43 mg dm -3 at the study site. Other authors have also associated soybean unresponsiveness with B foliar application to its low efficiency (Seidel et al, 2015;Bruns, 2017;Nakao et al, 2018;Santos et al, 2019;Ratke et al, 2020).…”

The efficiency of the boron (B) nutritional status in soybean (Glycine max (L.) Merr.) was evaluated by degree of agreement (DA) indicators using different diagnostic methods and by prescient diagnostic analysis (PDA). The objective of this study was to evaluate the efficiency of two interpretation methods of B nutritional status in soybean, that is, compositional nutrient diagnosis (CND) and critical level (CL). An experimental trial was conducted using a randomized block design with five replicates, which evaluated foliar B application rates of 0, 300, 600, 1200, and 1800 g ha -1 . Another study consisted of monitoring 140 commercial farms. We sampled leaves to determine nutrient contents and estimate yield in both studies. All samples were diagnosed by CND and CL methods. A reference value in the literature was obtained by the reduced normal distribution and CL methods by field calibration in the experimental trial. All the methods showed a high DA between diagnoses; the efficiency ratio and accuracy for true deficiency were both low, except for the CL method by field calibration, which exhibited an increase in positive net yield. The DA was ineffective to validate the efficiency of nutritional diagnoses; methods with a higher DA showed negative values for the net increase in production (-46 to -53 kg ha -1 ). The CL method by field calibration showed greater efficiency in assessing the nutritional status of B in foliar fertilized soybean because the net increase in production was 197 kg ha -1 .

“…Manganese in soybean crops is applied through foliar application in the form of manganese sulfate. Manganese availability to soybean crops depends particularly upon tillage, organic matter content, and tillage [48]. e problem of manganese deficiency is more common in areas having flood and water fluctuations.…”

“…According to [23], 55 g of boron is required to produce one ton of soybean seed yield. Boron uptake by the plants is in the form of boric acid (H 3 BO 3 ), which is available in soil solution in a soluble form [48]. e other important source of boron is soil organic matter, which becomes available through microbial activity.…”

Nutrient Management for Soybean Crops

Soybean is one of the most important pulse crops in the world which supplies most of the protein and oil requirements. The efficient production of soybean crops is a constraint, with several biotic factors, abiotic factors, and crop management practices. Nutrient management is one of the important aspects for achieving higher production of crops. Effective nutrient management helps to assure the required nutrients needed for the plant without causing a significant decrease in the yield of crops. In addition to this, managing the nutrient efficiently helps the crop to cope with several types of biotic and abiotic stress. For soybean crop, altogether fifteen nutrients are needed, which comprises six macronutrients, namely, nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur, which are required relatively in large amounts, and nine micronutrients which include iron, boron, zinc, cobalt, copper, manganese, molybdenum, nickel, and chlorine. These nutrients can be supplied to the plants through soil incorporation or foliar spray of commercially available fertilizers. Nutrient requirements for soybean crops vary in concentration, and deviations can cause nutrient deficiency or toxicity in soybean crops. Nutrient availability to soybean crops depends on the available nutrients in the soil solution, the form of available soil nutrients, mode of uptake of nutrients, its interaction with other soil nutrients, soil chemistry, and method of fertilizer application. This review article explores essential nutrients for sustainable soybean production in relation to the role and functions of nutrients, required concentration, and visual syndrome shown during deficiency, including findings from several researches. The review article is aimed to guide soybean farmers for effective nutrient management and academicians in reviewing the literature in soybean nutrient management.
