Enzymatical activities and content of mineral nitrogen in soil after the application of two rates of different organic products

Agrochimica 42(6): 296-303

Enzymatical activities and content of mineral nitrogen in soil after the application of two rates of different organic products

Fourteen different organic products (composts, sludges and manures) were tested at rates of 25 and 50 t/ha in a greenhouse experiment on Lolium perenne, and residual amounts of mineral nitrogen and alkaline phosphatase and dehydrogenase activities in soil were measured. Generally, organic waste treatments improved growth and yield of L. perenne, with the exception of one product (urban refuse compost from Ador, Valencia) where instability was suspected.
