Phytomelioration of orchard agrocenosis as a way to enhance soil fertility and apple trees productivity

The results of a field experiment to study the effect grassing in orchard and microbial preparations (MP) have been presented article. was carried out Crimea on meadow alluvial calcareous soil. Mixtures herbs (MH) were investigated: MH2 - multiflorous ryegrass + blue alfalfa; MH3 fescue clover; MH4 alfalfa clover awnless rump. Control is natural (NG). MP used: Azotobacterin (AB) Complex (CMP). without use MP. When soil grassed with mixtures herbs, 1.8-3.3 times more plant residues added relative grassing, maximum mixture. Biologization led an increase fertility Corg by 0.57-0.60% nutrients: NO3- 47-86%; P2O5 34-155%; К2О 8-22%. This increases productivity apple trees 22–43%. combination CMP had greater content phosphorus potassium increased tree extent.
