Understanding phosphorus (P) dynamics in tropical sandy soil treated with organic residues of contrasting quality is crucial for P management using organic amendments. This research determined P fractions in a tropical sandy soil under the applicatio

This study evaluated the influences of biochar made from local agricultural wastes on sandy soils in farmer fields where biochar has been used as a soil amendment for more than three years. The major objective of this study was to gain insight into t

Publikováno v: Geoderma. 408:115590
Growing demands for crops have expanded agricultural production to sandy soils with low available phosphorus (P) content and high P mobility. Knowledge of P speciation and solubility in such soils is poorly understood. Here we investigated: i) the P

Dissolution of K, Ca, and P from biochar grains in tropical soils
Autor: Irb Kheoruenromne, Tanawan Limwikran, N. Prakongkep, Anchalee Suddhiprakarn, Robert Gilkes
Publikováno v: Geoderma. 312:139-150
Many biochars contain considerable amounts of plant nutrient elements in both water soluble and insoluble compounds but little is known of the rate of release of these elements to soil. This laboratory research incubated nine biochars produced from t

How the unique properties of soil kaolin affect the fertility of tropical soils
Autor: N. Prakongkep, Robert Gilkes
Publikováno v: Applied Clay Science. 131:100-106
The kaolin (s.l.) in many tropical soils is distinctly different from most specimen and industrial kaolins. Crystal structure is highly disordered and crystal sizes are much smaller than for specimen and industrial kaolins. The crystal habit of soil

Biochar may contain substantial amounts of plant nutrient elements, and at typical rates of application, may supply luxury levels of K, Ca, P, and other plant nutrients. However, little is known of the agronomic effectiveness of these nutrients becau

Pyrite and other sulphur minerals in giant aquic spodosols, Western Australia
Autor: Robert Gilkes, N. Prakongkep, Stephen Wong, Balbir Singh
Publikováno v: Geoderma. :78-90
Thirty very deep aquic spodosols in swales of the Bassendean Dune System, Western Australia were investigated for their potential to acidify due to their contents of acid-forming sulphur minerals. Pyrite commonly occurs in B, Bh, C and sometimes A an
