The form of sulfur fertilizer can influence its behavior and crop response. A growth chamber study was conducted to evaluate five sulfur fertilizer forms (ammonium-sulfate, ammonium-thiosulfate, gypsum, potassium-sulfate and elemental-sulfur) applied in seed row at 20 kg S ha⁻¹ alone, and in combination with 20 kg phosphorus pentoxide (P2O5) ha⁻¹,...
The potential of biochar to improve numerous soil physical, chemical and biological properties is well known. However, previous research has concentrated on old and highly weathered tropical soils with poor fertility, while reports regarding the influence of biochar application on relatively young and fertile temperate prairie soils are limited. Fu...
Biochar applications have proven effective in highly weathered tropical and subtropical soils. However, less is known about how different biochars behave as amendments when added to temperate soils. Previously, studies have used high biochar rates (tens to hundred t ha-1) but such high rates are impractical for farm application because of its low d...
In this study, we investigated N2O emissions from two fields under minimum tillage, cropped with maize (MT maize) and summer oats (MT oats), and a conventionally
tilled field cropped with maize (CT maize). Nitrous oxide losses from the MT maize and MT oats fields (5.27 and 3.64kg N2O-N ha−1, respectively) were significantly higher than those from t...
An experiment was conducted to evaluate some organic wastes namely; brans of wheat, rice, grass pea, tea waste colonizing with and without a bio-control agent T. harzianum and seed treatment with vitavax-200 and T. viride in controlling seedling mortality caused by artificially inoculated of Sclerotium. rolfsii and yield performance of wheat in fie...
