INFLUENCE OF THE ORGANIC FERTILIZERS AND AMELIORANTS ON THE SOUTHERN CHERNOZEM BUFFER PROPERTIES
Influence of the organic fertilizers and ameliorants on the southern chernozem buffer properties is studied. Application of quagmire and sapropel, as well as seeding the sweet clover was the most effective to increase the overall buffer capacity, correlated to the soil humus status indicators. Quagmire and sapropel can be used as alternative sources of humus in a deficit of manure.
