Feather hydrolysate as a promising nitrogen-rich fertilizer for greenhouse lettuce cultivation

NEW NKSMg FERTILIZER FROM FEATHER HYDROLYSATE: POT EXPERIMENTS

EXTENDED ABSTRACT The method of new NKSMg fertilizer based on utilization of feather waste from slaughterhouses was presented. The method allows the production of liquid fertilizers which can be used in soil and foliar application. The whole process is based on the digestion of feather waste by acid hydrolysis, adjusting pH of the reaction medium, and then enriched in selected nutrients. Pot ex...

Camphor as a promising insecticude for control

Biochar and nitrogen fertilizer alters soil nitrogen dynamics and greenhouse gas fluxes from two temperate soils.

Biochar (BC) application to agricultural soils could potentially sequester recalcitrant C, increase N retention, increase water holding capacity, and decrease greenhouse gas (GHG) emissions. Biochar addition to soils can alter soil N cycling and in some cases decrease extractable mineral N (NO and NH) and NO emissions. These benefits are not uniformly observed across varying soil types, N ferti...

Porcine Hemoglobin Hydrolysate as a Biostimulant for Lettuce Plants Subjected to Conditions of Thermal Stress

The effects of different kinds of biotic and abiotic stress on crops can be lessened through exogenous application of different biostimulant products. Although some of these products come from enzymatic hydrolysates derived from animal remains, the literature does not contain references to the use of enzymatic hydrolysates obtained from animal hemoglobin, specifi cally porcine blood. With the a...

Nitrogen Response Index as a Guide to Fertilizer Management

The efficiency with which fertilizer-nitrogen (N) is transferred to grain-N in cereals is usually less than 50% and averages 33% worldwide. Two long-term N fertility experiments were evaluated to examine temporal changes in nitrogen use efficiency (NUE) and their causes. Averaged over 30-yr, non-irrigated winter wheat NUE was 49% at a 22.4 kg N ha 1 yr 1 rate and decreased to 34% at a rate of 1...
