Understanding Marginal Lands ande the Urgent Need for Resilient Crops

Marginal lands concludes a broad category of agricultural areas where conventional crop production is severely limite byabiotic stresses. These included arid andd semi- arid regions with chronoid water scarcity, saline or alkaline soils that difficir root function, acid soils with alumm toxity, shallow w or degradided soils low in organic matter, and lands prone to fooding or extreme flukture valigations.
