Morphological and Physiological Responses of Carnation and Tomato to Organic Phosphorus Insecticides and Inorganic Soil Phosphorus.
During the last few years considerable attention has been focused upon the use of the organic phosphorus compounds hexaethyl tetraphosphate and tetraethyl pyrophosphate as the active components of certain commercial insecticides. These substances are known to be toxic not only to insects but to other organisms in general as well. As the names of hexaethyl tetraphosphate and tetraethyl pyrophosp...
متن کاملColloidal and dissolved phosphorus in sandy soils as affected by phosphorus saturation.
Fertilization exceeding crop requirements causes an accumulation of phosphorus (P) in soils, which might increase concentrations of dissolved and colloidal P in drainage. We sampled soils classified as Typic Haplorthods from four fertilization experiments to test (i) whether increasing degrees of phosphorus saturation (DPS) increase concentrations of dissolved and colloidal P, and (ii) if criti...
متن کاملSoil Phosphorus Dynamics under Sprinkler and Furrow Irrigation
Furrow irrigation detaches and transports soil particles and subsequently nutrients such as phosphorus (P). To reduce the risk of erosion and offsite P movement, producers can convert from furrow to sprinkler irrigation. We completed research on soil P dynamics in furrow versus sprinkler irrigated soils from four paired fields in south central Idaho. Surface soils (0-2.5 inches) were obtained f...
متن کاملSoil test phosphorus and cumulative phosphorus budgets in fertilized grassland
We analyzed the linearity of relationships between soil test P (STP) and cumulative phosphorus (P) budget using data from six long-term fertilized grassland sites in four countries: France (Ercé and Gramond), Switzerland (Les Verrières), Canada (Lévis), and Finland (Maaninka and Siikajoki). STP was determined according to existing national guidelines. A linear-plateau model was used to determin...
متن کاملPearl Millet Growth as Affected by Phosphorus and Water
The interaction of soiil water and P supply is of paramount importance to pearl millet [Penniseturn gluucum (L.) R. Br.] growth in Sahelian Africa due to unreliable rainfall and low soil P availability. This study was conducted to quantify the growth response of pe:ul millet to water supply and P under conditions analogous to the Saliel in terms of climatle and soil. Millet was grown for 84 d i...
