Crop Modelling for Decision Support Systems

These flashcards cover important vocabulary and concepts related to nitrogen modelling and crop management systems as discussed in the lecture.

N modelling

The use of nitrogen model simulations to understand agricultural processes, analyze systems, and provide decision support.

RB209

The UK fertilizer manual that provides guidelines for fertilizer application rates.

EUrotate model

A crop rotation simulation model aimed at providing farm advice, especially regarding nitrogen management and crop rotations.

Mechanistic models

Models that simulate biological processes to predict crop growth and nutrient dynamics.

Nmin method

A decision support method focusing on predicted versus measured mineral nitrogen in the soil.

Soil pH

The measure of acidity or alkalinity of the soil, affecting nutrient availability.

Fertilizer recovery

The efficiency of plants to utilize applied fertilizer nitrogen.

Crop diversity

The variety of crops grown in a specific area, which can influence nutrient management strategies.

Catch crop

A crop grown to absorb nutrients, particularly nitrogen, and reduce leaching losses.

Target yield approach

A method for estimating crop nitrogen requirements based on expected yields.

Decision support systems

Systems that analyze data and provide recommendations to aid decision-making in agriculture.
