Whey utilization in furrow irrigation: effects on aggregate stability and erosion.
Improving soil structure often reduces furrow erosion and maintains adequate infiltration. Cottage cheese whey, the liquid byproduct from cottage cheese manufacture, was utilized to stabilize soil aggregates and reduce sediment losses from furrow irrigation. We applied either 2.4 or 1.9L of whey per meter of furrow (3.15 or 2.49Lm(-2), respectively) by gravity flow without incorporation to two ...
متن کاملModelling Furrow Irrigation-Induced Erosion on a Sandy Loam Soil in Samaru, Northern Nigeria
Assessment of soil erosion and sediment yield in furrow irrigation is limited in Samaru-Zaria. Data was collected in 2009 and 2010 and was used to develop a dimensionless model for predicting furrow irrigation-induced erosion (FIIE) using the dimensional analyses approach considering stream size, furrow length, furrow width, soil infiltration rate, hydraulic shear stress, soil erodibility, and ...
متن کاملBromoxynil degradation in a Mississippi silt loam soil.
BACKGROUND The objectives of these laboratory experiments were: (1) to assess bromoxynil sorption, mineralization, bound residue formation and extractable residue persistence in a Dundee silt loam collected from 0-2 cm and 2-10 cm depths under continuous conventional tillage and no-tillage; (2) to assess the effects of autoclaving on bromoxynil mineralization and bound residue formation; (3) to...
متن کاملEffect of soil structure breakdown on splash erosion in different soil textures
This study was carried out to investigate the role of soil structure in splash erosion in semi-arid soils. Splash erosion was measured in four soil textures (silty clay loam, sandy clay loam, silt loam and sandy loam) with two soil structure conditions (with natural structure and under aggregate breakdown) using a simulated rainfall with 50 mmh-1 in intensity for 30 min in splash caps with 10-c...
متن کاملSeeded, Delayed-Flood Rice on a Silt-Loam Soil
Urea is the most widely used nitrogen (N) fertilizer in direct-seeded, delayed-flood rice production. Urea fertilizer is susceptible to loss as ammonia gas to the atmosphere if not flooded in a timely manner. A urease inhibitor [i.e. N-(n-butyl) thiophosphorictriamide; NBPT] is recommended when a timely flood cannot be established. Recent research has indicated that when relative humidity (RH) ...
