Journal ArticleDOI
Evaluation of human urine as a source of nutrients for selected vegetables and maize under tunnel house conditions in the Eastern Cape, South Africa.
TL;DR: Generally the results showed that human urine compared well with urea as a source of N for crops but optimum rates depend on the sensitivity of the crops to soil salinity, which should be monitored where human urine is regularly used for fertilizing crops.
Journal ArticleDOI
Mulch effects on soil moisture and nitrogen, weed growth and irrigated maize productivity in a warm-temperate climate of South Africa
TL;DR: Grazing vetch and forage pea mulch significantly reduces maize yields on smallholder irrigation schemes in South Africa and benefits from different types of mulch are not well understood, leading to challenges in selecting the most appropriate cover crop species to grow.
Journal ArticleDOI
Conservation agriculture effects on soil organic matter on a Haplic Cambisol after four years of maize–oat and maize–grazing vetch rotations in South Africa
TL;DR: While total SOM was more concentrated in the 0–5 cm soil depth across treatments, a lack of maize fertilization (F2 and F4 regimes) significantly reduced total SOM significantly.
Journal ArticleDOI
Microbial utilisation of two proteins adsorbed to a vertisol clay fraction: toxin from Bacillus thuringiensis subsp. tenebrionis and bovine serum albumin
Tiphaine Chevallier,Tiphaine Chevallier,Pardon Muchaonyerwa,Pardon Muchaonyerwa,Claire Chenu +4 more
TL;DR: The inhibitory effect of clays on utilisation of BSA and Btt toxin was interpreted as being the result of the adsorption of the proteins to clay, which rendered the proteins unavailable for microbial utilisation.
Journal ArticleDOI
Decomposition, nitrogen and phosphorus mineralization from winter-grown cover crop residues and suitability for a smallholder farming system in South Africa
TL;DR: Grazing vetch and forage pea residues resulted in higher N contribution to maize stover than oat residues, and farmers may use grazing vetch for improvement of soil mineral N while oats may result in enhancement of soil organic matter and reduction land degradation because of their slow decomposition.
