Potassium and Sulphur response in barley locations
Aims
To evaluate any respose in growth and yield of barley to potassium and sulphur products in leaching sand loam
Key messages
Significant yield responses were observed indicating that lentisl can respond to K & S application during the growing season where soil nureition levels are depleted
