متن کاملManure Management regarding Nitrogen Compounds
This chapter considers the emissions of ammonia (NH 3) and nitrous oxide (N 2 O) from the excreta of agricultural animals deposited in buildings and collected as either liquid slurry or solid manure. This includes emissions from animal excreta at all stages: animal housing, manure storage and from land spreading of manures. Excreta deposited in fields by grazing animals are dealt with under SNA...
متن کاملCalibration and Algorithm Development for Estimation of Nitrogen in Wheat Crop Using Tractor Mounted N-Sensor
The experiment was planned to investigate the tractor mounted N-sensor (Make Yara International) to predict nitrogen (N) for wheat crop under different nitrogen levels. It was observed that, for tractor mounted N-sensor, spectrometers can scan about 32% of total area of crop under consideration. An algorithm was developed using a linear relationship between sensor sufficiency index (SIsensor) a...
متن کاملOptical Sensor-Based Algorithm for Crop Nitrogen Fertilization*
Nitrogen (N) fertilization for cereal crop production does not follow any kind of generalized methodology that guarantees maximum nitrogen use efficiency (NUE). The objective of this work was to amalgamate some of the current concepts for N management in cereal production into an applied algorithm. This work at Oklahoma State University from 1992 to present has focused primarily on the use of o...
متن کاملMANURE MANAGEMENT Differential Nitrogen-15 Labeling of Dairy Manure Components for Nitrogen Cycling Studies
proach, 12 to 63% of dairy manure N may be taken up by corn during the first growing season after application Current estimates of dairy manure nitrogen availability to crops (Motavalli et al., 1989; Klausner et al., 1994). Nutrient are based on indirect measures and vary greatly. The objective of this study was to differentially label dairy manure N components with the availability in the seco...
