We are planting 5000 Nos of Moringa plants. For the pit preparation, we do not have access to large quantities of farmyard manure and we cannot afford to spend on purchasing expensive organic composts. Can we use humic acid as an alternative to either farmyard manure or organic compost for the pit preparation. I shall appreciate feedback & views from members of this forum if we can use humic acid as an alternative to either farmyard manure or organic compost
