Terms and concepts
Full dictionary →Phytotoxicity
Phytotoxicity is the capacity of a substance or environmental condition to cause damage, growth inhibition, or death in plants.
DetailsAdjuvant
A substance added to a pesticide spray mixture to improve the performance, physical properties, or biological activity of the active ingredient.
DetailsPesticide load
It is a measure of the total amount and frequency of pesticide active ingredients applied to a specific area over a given timeframe.
DetailsHerbicidal effect
This is the pronounced inhibitory or lethal impact of a chemical agent on the growth and vital functions of weeds.
DetailsPlough pan
A plough pan is a compacted soil layer formed below the depth of cultivation, caused by the repetitive mechanical pressure of tillage equipment.
DetailsMinimum tillage
A conservation tillage system that reduces the frequency and depth of mechanical soil disturbance to improve soil structure and moisture retention.
DetailsSoil aggregate
A soil aggregate is a cluster of soil particles held together by organic matter, roots, and clays, essential for soil aeration and water retention.
DetailsCover crops
These are plants grown primarily to protect and enrich the soil rather than for harvest, serving to prevent erosion, suppress weeds, and improve soil health between main crop cycles.
DetailsSoil hydraulic conductivity
The ability of a soil to transmit water through its profile when subjected to surface irrigation or precipitation.
DetailsHumification
The biochemical process of decomposing organic matter into stable humus compounds that improve soil fertility and structure.
DetailsField emergence
It is the percentage of planted seeds that successfully produce seedlings under actual field conditions, reflecting the combined impact of seed quality and environment.
