The content of plant nutrients in soil and the productivity of grasslands in organic and conventional farming in Estonia

2001

Ellermaee, O. (Estonian Agricultural Univ., Tartu (Estonia). Dept. of Grassland Science and Botany) | Geherman, V.

The general purpose was to study productivity of organic grasslands and compare it with productivity at a conventional farm under the same or similar climatic and pedologic conditions. The investigation was based on field experiments that were carried out in 5 different regions of Estonia in 2000. In the current research, the DM-yield of sward (on 4 research plots of 5 square m), the botanical composition, soil pHKCL and humus content (by Tjurin) were measured. Also the content of soluble plant nutrients P and K were measured by DL-(Egner-Riehm) method and Ca and Mg- by AL- (ammonium acetate extraction) method.
