ABSTRACT
Weeds are undesirable plants that competed for resources with crops; thus, researching their nutritional properties contributed to establishing efficient management techniques. Different nutritional contents of weed species affect their competitiveness and susceptibility to various treatment techniques. The NPK concentrations varied significantly among weed species. Top of FormTop of FormWeeds were transformed into value-added compost by exploiting their organic content to produce a nutrient-rich soil supplement. Weeds, commonly viewed as agricultural nuisances, were successfully recycled by composting, a process that accelerates decomposition and converts organic materials into stable humus. The composting reduced garbage while producing a valuable product that improved soil fertility and health also. In this investigation, weed plants were obtained from the areas of Mullana, Ambala, Haryana. The collected weed plant samples were analyzed for physical, chemical and biological parameters such as pH, electrical conductivity (EC), moisture content (MC), plant nutritional parameters (nitrogen, phosphorus, potassium) as per the procedure documented by Indian Standards. The noxious weeds Parthenium hysterophorous, Solanum nigrum, Calotropis procera and Trianthema portuculacastrum, collected and cut into little fragments, about 1 cm in size. After that, the chopped biomass was placed in a pit for a composting experiment after a week of drying. After the 200 days of composting pH, EC, MC and TOC, total nitrogen and accessible phosphorus (P available) were all measured on one portion that had been air-dried.
Key words: Weeds, NPK, value-added compost, humus, soil fertility, physical, chemical, biological parameters
