Effect of Mg-Modified Waste Straw Biochar on the Chemical and Biological Properties of Acidic Soils

Molecules, 2023
Biochar is important for soil improvement, fertilizer innovation, and greenhouse gas reduction. In this paper, Mg-modified biochar was prepared from rice and corn straw and mixed with soil at a 1% (w/w) addition in an indoor soil simulation experiment to

Quantifying mineral sources of potassium in agricultural soils [PDF]

, 2008
Soil potassium (K) reserves are crucial for crop quality and yield in low input agricultural systems. Soils contain varying amounts of K-bearing minerals and differ in their inherent K supply capacity.

Potassium availability and soil extraction tests in agricultural soils with low exchangeable potassium content [PDF]

Plant, Soil and Environment, 2015
Low application of fertilizer potassium (K) in intensive agriculture leads to a gradual decrease and, afterwards, to a steady state of soil K determined by tests which are based on soil exchangeable K (Kexch) extraction. In this situation, non-exchangeable K (Knon-exch) is being released and therefore real plant availability does not necessarily ...

Effects of steam sterilization on soil abiotic and biotic properties

Soil Organisms, 2020
Experiments under natural conditions are becoming increasingly important to investigate the impacts of global change on biodiversity and ecosystem functioning, but field experiments are not always feasible. Climate or biodiversity chamber experiments can

Evaluating Calibration and Spectral Variable Selection Methods for Predicting Three Soil Nutrients Using Vis-NIR Spectroscopy

Remote Sensing, 2021
Soil nutrients, including soil available potassium (SAK), soil available phosphorous (SAP), and soil organic matter (SOM), play an important role in farmland soil productivity, food security, and agricultural management. Spectroscopic analysis has proven

The effect of different rates and forms of sulphur applied on changes of soil agrochemical properties

Plant, Soil and Environment, 2008
A three-year field experiment was conducted from 2000 to 2002 in North-East Poland. Each year three sulphur fertilization rates in the form of sulphate (S-SO2-4) and pure (S-S0) sulphur were applied: 40, 80 and 120 kg/ha. In the soil horizon at the depth
