Nutrient Availability to Corn From Dairy Manures and Fertilizer in a Calcareous Soil
The expansion of the dairy industry in southern Idaho has led to increased application of manures to meet crop nutrient demands that can alter the uptake pattern of both macronutrients and micronutrients. A greenhouse study was conducted to determine the effects of dairy manure, composted dairy manure, and fertilizer (monoammonium phosphate) application on soil test phosphorus (P), microbial ac...

متن کاملPredicting Soil Phosphorus Fertilizer Rate Using Hierarchical Segmented Regression Models
Predicting soil phosphorus (P) needs and P fertilizer requirements is important for plant nutrition and reducing environmental risk. The P requirement (PR) can be calculated from three components: the current status of soil P (P0), soil P buffer coefficient (PBC), and the soil P critical level (PCL). The PBC and PCL can be predicted from soil clay content using linear-plateau models. The PR, PB...
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 کاملRelationship between soil test phosphorus and phosphorus in runoff: effects of soil series variability.
Phosphorus loss in runoff from agricultural fields has been identified as an important contributor to eutrophication. The objective of this research was to determine the relationship between phosphorus (P) in runoff from a benchmark soil (Cecil sandy loam; fine, kaolinitic, thermic Typic Kanhapludult) and Mehlich III-, deionized water-, and Fe(2)O(3)-extractable soil P, and degree of phosphorus...
