Sugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand Soils
Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate t...
متن کاملOrganic Amendments Enhance Biological Suppression of Plant-parasitic Nematodes in Sugarcane Soils
Previous research has shown that population densities of plant-parasitic nematodes are reduced when a legume crop is grown in rotation with sugarcane. However, this effect is only temporary, as nematodes usually return to high densities within 12 months of planting sugarcane. This rapid resurgence suggests that natural enemies that normally keep plant-parasitic nematodes under control in natura...
متن کاملLeaf Phosphorus Diagnosis of Sugarcane on Organic Soils
Most of the sugarcane (interspecific hybrids of Saccharum sp.) production in Florida is on organic soils. Supplemental phosphorus (P) fertilizer is often applied for optimum yields, but producers are required to reduce P levels in farm drainage waters. The objectives of this study were to relate optimum leaf P tissue concentration with yield in organic soil, and to determine optimum leaf sampli...
متن کاملThe Effect of Different Furrow Irrigation Regimes on Infiltration and Sugarcane Yield at Ubombo
In surface irrigation, the soil serves as a medium for infiltration and conveying water from upstream to the downstream end of a field. In this study, infiltration properties of the Sibaya (Si) soil series (Glenrosa in the South African soil classification system) were determined by a volume balance method using a two-point approach technique. The purpose of the study was to examine the effect ...
متن کاملSorption-desorption behavior of atrazine on soils subjected to different organic long-term amendments.
Sorption of atrazine on soils subjected to three different organic amendments was measured using a batch equilibrium technique. A higher K(F) value (2.20 kg(-1)(mg L(-1))(-N)) was obtained for soil fertilized with compost, which had a higher organic matter (OM) content. A correlation between the K(FOC) values and the percentage of aromatic carbon in OM was observed. The highest K(FOC) value was...
