Oversupply occurs when amendments are added in excess of crop requirements, as may happen when manure is applied to satisfy the nitrogen requirements of crops [5, 6].
Plant-available N and PMN were greater in RT compared with CP at V6, suggesting RT increases synchrony of soil N availability with crop requirements.
Weather parameters chosen for the index affect crop development through its life cycle (phenological phases) and reflect crop requirements for achieving full maturity and yield.
Equation 8 shows the water crop requirements for a decade ((w_{{{text{a}}i}} )), restricted to decade water availability((W_{ij} )).
The greenhouse was not heated, watering was carried out by drip irrigation, according to crop requirements, and weed control was carried out in a manual way.
It is however not clear from this study how the different water levels applied are related to crop requirements and actual water use efficiency.
Matching the crop requirements with soil characteristics, optimum cropping pattern was obtained for wheat, corn, melon, potatoes, sunflower, sugar beet, Alfalfa, peach, citrus, and olive.
The presented work shows how irrigation requirement can be calculated combining regional projections of climate conditions specified as long-term 'scenario-weather', combined with crop requirements and management, and soil conditions.
To ensure application of solid fraction was in compliance with crop requirements and regulations, the spreader was equipped with an electronic rate control system enabling target nutrient rates ranging from 10 to 120 kg [N] ha−1.
Satellite assessment of aboveground plant residue mass and quality is essential for agro-ecosystem management of organic nitrogen (N) because growers credit a portion of residue N towards crop requirements the following spring.
