Using Selected Structural Indices to Pinpoint the Field Moisture Capacity of Some Coarse-Textured Agricultural Soils in Southeastern Nigeria
Igwe, Charles Arizechukwu, Hermansah, ., Obi, Martin Eze
Over- or underestimation of field capacity (FC) of agricultural soils could misguide soil and water management and this might have negative agronomic and environmental impacts. The study sought to identify the moisture tension for reliably estimating in the laboratory the FC of some sandy soils with...

The Application of Rice Hull Mulch and Potassium Nitrate on Growth and Yield of Kailan (Brassica oleraceae var. Long Leaf)
Ramadiana, Sri
Potassium (K) is absorbed by plants in larger amounts than any other mineral element except N to optimalize plant growth. Mulches may be influenced an available K at vegetative growth phase of plant. The research was conducted in Simpang Kanan Village, Gisting, Tanggamus Lampung Province. The object...

Determination and Prediction of Some Soil Properties using Partial Least Square (PLS) Calibration and Mid-Infra Red (MIR) Spectroscopy Analysis
Djuuna, Irnanda Aiko Fifi, Abbott, Lynette, Russell, Craig
Soil chemical, physical and biological analyses are a crucial but often expensive and time-consuming step in the characterization of soils. Rapid and accurate predictions and relatively simple methods are ideally needed for soil analysis. The objective of this study was to predict some soil properti...
