A major survey has revealed that two thirds of all UK soils are deficient in the key nutrients of magnesium, phosphorus and potassium. The results were delivered by NRM Laboratories, courtesy of the company’s annual soil summary report for 2024-2024 and reflect a trend that stretches back almost three decades. WebSample Depth. The normal sampling depth for nutrients is about 15 cm (6 in.) because most plant roots grow to that depth, and tillage mixes most nutrients into the soil to about 15 cm deep. Subsoil is normally much lower in nutrient content, so sampling too deep will produce a sample that is not representative of the field. how atm machine network works
