🌱 Organic Fertilizers & Biofertilizers | જૈવિક ખાતરો અને બાયોફર્ટિલાઇઝર્સ

Introduction | પરિચય

Healthy plants need healthy soil, balanced nutrition and beneficial microorganisms.

Organic fertilizers and biofertilizers play an important role in sustainable agriculture, organic farming and kitchen gardening. They help improve soil fertility, nutrient availability and biological activity.

તંદુરસ્ત છોડ માટે તંદુરસ્ત જમીન, સંતુલિત પોષણ અને ઉપયોગી સૂક્ષ્મજીવો ખૂબ જરૂરી છે.

જૈવિક ખાતરો અને બાયોફર્ટિલાઇઝર્સ જમીનની ફળદ્રુપતા જાળવવામાં, છોડને પોષક તત્ત્વો ઉપલબ્ધ કરાવવામાં અને જમીનમાં ઉપયોગી સૂક્ષ્મજીવોની સંખ્યા વધારવામાં મદદરૂપ થાય છે.

આપણે વિવિધ પ્રકારનાં Organic Fertilizers અને Biofertilizers વિશે વિગતવાર જાણીએ.

1. What are Organic Fertilizers? | જૈવિક ખાતરો શું છે?

Organic fertilizers are materials derived from plant, animal or natural organic sources that supply nutrients and organic matter to the soil.

જૈવિક ખાતરો એટલે વનસ્પતિ, પ્રાણી અથવા કુદરતી સ્રોતોમાંથી મળતાં એવા પદાર્થો જે જમીનમાં સેન્દ્રિય તત્ત્વો અને પોષક તત્ત્વો ઉમેરે છે.
