NEW NKSMg FERTILIZER FROM FEATHER HYDROLYSATE: POT EXPERIMENTS

چکیده
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 experiments have shown that the use of fertilizer from feather hydrolysate gave a significant effect of the increase of plant biomass. The content of nitrogen, potassium and magnesium in plants increased by 76.2%, 37.3% and 29.5% respectively compared to not fertilized plants. The use of NKSMg fertilizer also significantly modified the content of zinc and manganese in tested plants. The solution is currently in research-implementation stage.

Meat and bone meal (MBM) contains appreciable amounts of nitrogen (N), phosphorus and calcium making it interesting as fertilizer to various crops. The effect of Norwegian MBM as N fertilizer has been evaluated in pot and field experiments. The soils used in the pot experiment were peat and a sand/peat mixture, both low in content of plant nutrients. The field experiment was carried out on a si...

Several protein sources were tested as deer repellents with captive deer. Black-tailed deer were offered Western redcedar seedlings treated with corn gluten meal, feather meal, poultry blood, hydrolyzed casein, or a control (latex sticker used for treatment proteins). After 37 days, feather meal and hydrolyzed casein provided equivalent protection against browse damage (only 23% of seedlings si...

The biodegradability of three types of bioplastic pots was evaluated by measuring carbon dioxide produced from lab-scale compost reactors containing mixtures of pot fragments and compost inoculum held at 58 °C for 60 days. Biodegradability of pot type A (composed of 100% polylactic acid (PLA)) was very low (13 ± 3%) compared to literature values for other PLA materials. Near infrared spectrosco...

Field plot experiments were conducted over 3 years (from April 2014 to November 2016) in a double-rice (Oryza sativa L.) cropping system in subtropical China to evaluate the effects of N fertilizer placement on grain yield and N recovery efficiency (NRE). Different N application methods included: no N application (CK); N broadcast application (NBP); N and NPK deep placement (NDP and NPKDP, resp...
