THE EFFECT OF MULCHING ON THE BEHAVIOUR OF SOME NUTRIENT COMPOUNDS IN THE SOIL
Mulching may, for instance, produce an increase in the nutrient content of the soil by leaching of nutrients from the mulch, but at the same time the entire condition of nutrient availability may be modified for better or worse by changes induced by the mulch in the moisture and temperature regimes of the soil .
The study of factors determining the changes of nitrogen forms in the soil was followed by a number of agricultural measures, which influence those processes favourably. On the other hand ammonization and nitrification of nitrogen are connected with losses of that element. The amount of losses is determined by microbiological activity, by physical properties of the soil, by fertilizers used, by the level of nutrient compounds, by the temperature and moisture of the soil [2, 6, 9, 12, 15].
