Nitrogen balance as an indicator of the nitrate leaching risk

Original language description

Nitrogen balance on soil surface was calculated for 5 farms in the period of 3 years. Though there was no whole farm N balance exceeding the limit set to 50 kg ha-1 in whole 3 year period and only few of them in single year results, single field balanceexceeded the limit quite often. In case of high surplus the particular field can be the point where the loss occurs. On the two of farms were no fields with N balance higher than 50 kg ha-1 in several years in row. On the three examined farms was the limit exceeded on 32%, 12% and 41% of acreage in two years in row and on 1%, 0,5% and 10% in three years in row. On these fields is risk of leaching even higher. This kind of results is lost when only whole farm balance is taken into account. Nitrogen surplus does not have to mean loss of given amount of the nutrient because other important influences, like soil conditions, weather course and management practices, play their role. However such results indicate increased risk of leaching. Fu
