Abstract:

Spatial variability of leaf nutrients in oil palm (Elaeis guineensis Jacq.) plantations in Goa, Karnataka, Mizoram and Gujarat states of India were examined for implementation of site-specific fertilisation programs. Georeferenced leaf samples were collected randomly for the oil palm plantations. The leaf nutrient concentrations were assessed and analysed statistically and geostatistically. The concentrations of leaf nutrients such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S) and boron (B) in oil palm plantations varied widely at different locations.

Abstract:

Iron homeostasis is important in the human health system. Abnormal iron homeostasis, such as iron deficiency (ID), may cause diseases such as anemia. Iron status is a complex phenomenon that is influenced by a variety of factors, including nutrient intake. This research is needed to understand better the different nutrients which influence iron status and to develop effective strategies for improving iron status in at-risk populations. NHANES 2017-2020 data was used to simulate the linear regression model to predict the relationship between different nutrients the iron status. Results revealed

Soil analysis is used to estimate nutrient availability, but nutrient concentrations are not always related to yield in most fruit plants, including grapevines.

This paper aims to evaluate the nutrient K characteristics of paddy fields, the K contribution from irrigation water and harvested straw, and the response of fertilization to rice yields. The availability of K nutrients, apart from being influenced by clay mineral composition, clay

Field experiments were conducted to study the effect of P sources and levels in a maize -sunflower system. The results of the study revealed that, single super phosphate with or without microbial inoculants at recommended level of P,O, to maize, improved the available nutrient status of the soil. The soil nutrient status in sunflower crop and the uptake of nutrients in maize and sunflower increased with SSP with microbial-inoculants.

Abstract:

Soil and water pollution caused by excessive use of fertilizers and resource scarcity are critical issues in modern horticulture. Although laboratory tests are reliable, they take time and use chemical reagents that must be disposed of and complex protocols. Monitoring plant nutrient status through technologies that allow continuous and rapid assessment is crucial for precise resource management. Several proximal and remote sensors that use different physico-chemical principles to monitor plant nutrient status are available nowadays. However, these technologies still have important operative a

Rubber cultivation is primarily rainfed agriculture, which means that water supplies are not stable in most rubber cultivated areas. Therefore, improving the water use of rubber trees through fertilization management seems to be a breakthrough for enhancing the growth and latex yield of rubber trees and carrying out the intensive management of rubber agriculture. However, the relationships among the nutrient status of rubber trees, their water uptake, and soil resources, including water and nutrients, remain unclear.
