Palestinian farmer Mohsen Ahmed, 37, uses imported worms to produce organic fertilizers for plants, in Beit Lahia in the northern Gaza Strip on March 22, 2021. Organic fertilizers are beneficial for plants and vegetables and general human health. Vermic compost fertilizer is worm waste (the red wigler) that comes out of the worms after feeding on organic wastes and is treated and secreted by enzymes, hormones and amino acids inside the worm's digestive system.
