The Transport of Soil Nutrients

1969
The first stage in the transport of soil nutrients is their uptake into the root. This has been dealt with extensively elsewhere in this book but, to a lesser degree, it must be considered here, because transport across the cortex cannot be completely dissociated from the initial absorption.

Extraction and Integration of Different Soil Nutrient Grading Systems for Soil Nutrient Mapping

2016
These works present a model to integrate and harmonize different nutrient grading indexes originating from various existing soil polygon maps. The soil nutrient grading indexes might be different from one national soil survey to another and even be different for the different counties in the same national soil survey in China. Soil nutrients mapping in

Managing nutrients to mitigate soil pollution

Environmental Pollution, 2018
The health of soils is key not only to agricultural productivity, but to all the ecosystem services provided in terms of maintaining the quality of water, air, and food. Nutrient inputs to agricultural soils produce large benefits to human health, including the provisioning of calories and protein supporting at least half the human population ...

Chloride in soil: From nutrient to soil pollutant

Environmental and Experimental Botany, 2019
Abstract Chlorine is important for the fertility of soils being a nutrient for crops. However, anthropogenic activities often lead to excessive accumulation of the anion of chlorine, (Cl−) in soils, either directly by applying animal wastes that are usually rich in Cl− or via atmospheric depositions from industrial and municipal sources.

Nutrient balances and present state of available nutrients in the soil

2001
A widely accepted approach to evaluate the sustainability of agricultural production concerning the nutrient status is to calculate nutrient balances (= input — output of nutrients). For this it is necessary to register all nutrient outputs (uptake by main product and by-product, leaching) and nutrient inputs (use of fertilisers, atmospheric deposition,
