SAC Extends Its Catalogue Of Technical Notes

SAC News Release Ref. No: 09N81
Published: 11 Dec 2009

SAC has added 4 new Technical Notes to its extensive catalogue of short, practical field guides to key issues facing producers. SAC has a long history of providing such handy, easy-to-read advice, although nowadays it is published on the website rather than in printed form.

With funding from the Scottish Government under the Veterinary & Advisory Services (VAS) programme, the four latest publications deal with weed management in the potato crop and fertiliser recommendations for a range of crops.

TN621 Fertiliser Recommendations for Vegetables, Minority Arable Crops and Bulbs
TN623 Fertiliser Recommendations for Soft Fruit and Rhubarb Crops

The recommendations in these two technical notes are aimed at offering opportunities for the best financial return for the farmer or grower.  Adoption of the recommendations is consistent with the new NVZ Action Programme rules, which helps to minimise losses of nitrogen to the environment. Both these technical notes were funded by the Scottish Government as part of its Pollution Prevention Advisory Activity.

TN624 Weed Control in the Potato Crop

This new technical note takes account of the constantly changing legislative environment which has resulted in there being fewer herbicide options since the last technical note on this subject.  It covers conventional herbicide options in the potato crop but has potential interest to organic systems. This technical note was funded by the Scottish Government as part of its Crop Health Advisory Activity.

TN625 Nitrogen Recommendations for Cereals, Oilseed Rape and Potatoes

The Nitrogen (N) recommendations for cereals, oilseed rape and potatoes in this note have been updated in the light of recent trials results and advisory experience. The tables take account of N released from previous crop residues, grass leys and the N available from reserves in different soil types. The advice is consistent with the NVZ Action Programme rules. 

The volatility in prices for fertiliser and grain in recent years has accentuated the need for guidelines on adjusting for the break-even ratio (BER). BER is the ratio between the purchase price of the fertiliser per kg of N and the sale price per kg of the grain. It defines the point at which further expense on fertiliser is not worthwhile. This technical note was funded by the Scottish Government as part of its Pollution Prevention Advisory Activity.
