FIELD: agriculture, in particular, amelioration method used for creating of fertile layer on low-humus sandy soil. ^ SUBSTANCE: method involves applying lime and organic fertilizer into humus-depleted soil, said organic fertilizer being introduced in the form of ground plant remains and/or other forms in an amount of up to 40% the volume of ridges by distributing said fertilizer in furrows between ridges; forming ridges in the course of presowing treatment; applying layer of colmatant providing total volume of at least 20% the volume of pores of formed fertile layer; forming ridges with following breaking of formerly created ridges; embedding organic fertilizer and simultaneously applying biologically active preparation; 30-40 days later, reapplying organic fertilizer; reforming ridges and simultaneously irrigating ground organic with biologically active preparation; sowing seeds of cultured crops. ^ EFFECT: reduced time for creating on humus-depleted sandy soil of fertile layer adapted for immediate agricultural application, reduced wind and water erosion and provision for forming of recreational zones. ^ 1 ex |
