Nitrogen calculator for processing tomatoes

This calculator was developed based on results from a 3-year study in commercial subsurface-drip irrigated fields in the Central Valley and a replicated field trial at UC Davis.

Calculadora de nitrógeno para tomate industrial

Los cálculos se basan en datos de un estudio en campos comerciales de tomates industrials con riego por goteo ubicados en el Valle Central de California.

Nitrogen Mineralization from Organic Amendments

The calculations in this tool are based on an analysis of 113 datasets from the scientific literature. Nitrogen mineralization rates are adjusted based on soil temperature data from local weather stations.

Mineralización del nitrógeno a partir de abonos orgánicos

Los cálculos de esta herramienta se basan en un análisis de 113 conjuntos de datos de la literatura científica. Los índices de mineralización del nitrógeno se ajustan en función de los datos de temperatura del suelo procedentes de las estaciones meteorológicas locales.

Nitrogen Calculator for Annual Crops

The calculator was developed with results from field trials in California. It currently determines the amount of fertilizer N required for grain corn, silage corn, sunflower, spring planted wheat and processing tomatoes.
