Chalk is the predominant natural liming material in East Anglia. The 1991 Fertiliser regulations specify that for a screened product classification, 98% must pass through a 45mm sieve. We only supply 25mm to dust or 14mm to dust grades which makes it an ideal material to apply to stubbles prior to ploughing. Typical NV of 45-46%.
Available as 6mm to dust, this finer material is excellent for quicker correction of low pH levels. The finer particle size gives a better coverage when spreading and we would recommend this grade for application after ploughing or for top dressing purposes. Typical NV of 48-50%. needham chalks Needham Chalks Hanslope
