HERBACEOUS CROP SYSTEMS

Modulo WEED MANAGEMENT TECHNIQUES AND FERTILISATION

Weed concept. Weed adaptation strategies. Seed bank: germination and physiological, environmental and agronomic factors. Population dynamics and agroecological factors influencing it. Competition and complementarity between crops and weeds: harms and benefits. Strategies and tactics for weed control: indirect or preventive; direct (mechanical, physical, chemical, biological, integrated). The agroecological approach in the management of crop weeds. Herbicides and plants: penetration, translocation, biotransformation, mechanisms of action, selectivity and efficacy. Dynamics of herbicides in the agroecosystem. The management of weeds in the main crops in the Mediterranean environment.

Fertility concept. Form and dynamics of nutritive elements in agroecosystems: nitrogen, phosphorus, potassium, sulphur, calcium and magnesium, microelements. Classification of fertilizers and agronomic management of fertilization: optimal technical dose, time and method of application. Efficiency and effectiveness of fertilization; effects on production and product quality. The agroecological approach in fertilization management. Fertilization in "organic" agriculture. Foliar fertilization and fertigation: advantages and disadvantages. The fertilization plan. Fertilization management in the main crops in the Mediterranean environment.
