“…Micronutrients and OM showed close relation (Figure 3). The available Fe increased as the OM increased, confirming the results found by Huichun et al (2015). This may be due to the OM decomposition, complexation and chelatization, the dissolution of the organic and humic acids produced during the decomposition process, and the transformation of the soil active OM, which increase Fe availability (Bernardi et al, 2015).…”

“…Floral abortion is one of the main problems that contribute to yield reduction, which may be correlated with the plants' nutritional imbalance (Perdoná et al, 2014). Organic matter has practically all the essential elements required by the plant, especially micronutrients (Oliveira et al, 2016), which affect plant development and the quality of the nuts produced (Huichun et al, 2015).…”

Soil fertility is the key to agricultural production. The spatial correlation and location of nutrients may significantly affect the yields. The objective of this work was to evaluate the variability and spatial correlation of iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), and organic matter (OM) with macadamia nut yield. The study was conducted in an Oxisol cultivated for 20 years with macadamia nut in São Mateus, state of Espírito Santo, Brazil. A 100 point grid was used comprising an area of 144 × 140 m with a minimum distance between points of 5 m, in which a single composite soil sample was collected from 0-0.20 m layer for chemical analysis of Fe, Cu, Mn, Zn and OM. Nuts under the canopy’s projection were harvested from February to June, 2015. The data were evaluated by geostatistical analysis using semivariograms, and kriging was used to map spatial distributions of nutrients and nut yield. All evaluated attributes showed strong or moderate spatial dependence structure. The OM was correlated positively with micronutrients, but only Zn was positively correlated with nut yield. Crossed semivariograms adequately explained the maps of Zn and Mn; and Fe showed opposite tendency for macadamia nut yield.

“…Information on the spatial distribution of soil micronutrients and their influencing factors are very important for soil management and sustainable agricultural production [1]. Agricultural practices in developing countries like China and India, still consist of small land holdings and intensive cropping [2,3]. It is necessary to understand the spatial variability of soil micronutrients in agricultural areas and improve management practices.…”

Information on the spatial variability of soil-available micronutrients is important for farming and soil management practices. As current knowledge of factors influencing soil available micro-nutrients in the long-term scales is limited, we analyzed 821 and 812 representative surface (0-20 cm) soil samples from five sub-catchments in the Ping Gu intermontane basin in Beijing, China in 2007 and 2017. The objectives of this study were to assess the temporal and spatial distribution characteristics of soil-available micronutrients (Cu, Zn, Fe and Mn) and their relationships with soil's chemical properties. The concentration of available Cu ranged from 1-2 mg·kg −1 distributing over a large area in 2007, but it was more than 2 mg·kg −1 in the hilly regions in 2017. The concentration of available Zn (>5 mg·kg −1 ) increased significantly from 2007 to 2017, and showed an uneven distribution. The distribution of available Fe and Mn decreased from the northeast to the southwest region of the study area between 2007 and 2017, this being consistent with the topography in this area. Soil's available P (AP) had a higher contribution to available Cu and Zn in different sub-catchments. In addition, soil pH had a significant negative influence on available Fe in sub-catchments 1, 2 and 3, and on available Mn in all sub-catchments, except for sub-catchment 4. Moreover, the effects of soil chemical properties on soil-available micronutrients increased in each sub-catchment from 2007 to 2017. We conclude that differences in soil properties and land-use types were the main reasons for the spatial variability of soil-available micronutrients in the Ping Gu intermontane basin.

“…It is an important source of bioavailable micronutrients and a shortage or surplus of bioavailable micronutrients in the soil limits growth of crops (Liu et al, 2004;Ye et al, 2015). Out of the 16 plants nutrients, zinc (Zn), copper (Cu), iodine (I), manganese (Mn), molybdenum (Mo), boron (B), iron (Fe) are among those referred to as micronutrients.…”

“…According to Rieuwerts, Ashmore, Farago, and Thomton (2006) and Zhao, Liu, Xua, and Selim (2010), pH is the most important predictor for the estimation of extractable heavy metals from soil because of its strong effects on speciation, solubility and their bioavailability in soil solution. The capacity of a soil to supply microelements directly influences plant structural development and physiological function, regulates plant growth and development and product quality (Ye et al, 2015).…”

Soil degradation reduces agricultural productivity and poses a great threat on food security status of households. In Kenya, farmers have for a long time been using only nitrogen and phosphorous based fertilizers oblivious of the soil fertility status. In most cases, there has been lack of plant response to these fertilizers, which could be due to a limitation of nutrients other than nitrogen and phosphorous. Soils are considered as variable natural bodies because of combined intrinsic and extrinsic factors of different intensities at a field or a larger region scale therefore an understanding of such variability is imperative to provide insights needed in their management. This study was thus initiated to assess the availability of soil micronutrients from rice growing Vertisols in the Mwea irrigation scheme. Top (0-15 cm) soil samples were collected across paddy fields in the irrigation scheme and analyzed for iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) by the 0.1 N HCl extraction method. Soil pH (water and 1 M KCl) was also measured using the glass electrode pH meter. Soil solution pH ranged from 4.56 to 8.05 and 3.33 to 6.63 for water and 1 M KCl respectively. Soil Fe, Zn, Cu and Mn concentration varied greatly and ranged from undetected to 1360.6, 0.12 to 8.00, undetected to 9.29 and 1.50 to 849.2 mg/kg respectively. Coefficient of variations (CVs) for soil micronutrients ranged from 64% to 154% indicating very high variability. Soil pH was least variable with CVs 12% and 15% for water and KCl respectively. These results imply that the paddy soils in Mwea region are highly heterogeneous and soil micronutrients are enriched in some areas and depleted in others due to farm management practices and soil properties. Averagely, soil available Zn was deficient across the scheme and as such Zn fertilization can be effective in increasing soil Zn concentration and availability in the soil-root interface further enhancing soil productivity and yield quality. Attention should also be paid to appropriate farm management practices to avoid accumulation or depletion of nutrients.
