Fleece

Agricultural Fleece was first developed in the early eighties by Fiberweb France to allow growers to harvest their crops earlier and extend their growing seasons.

For the past 30 years Fiberweb have remained the worldwide market leaders in agricultural fleece. Today their world famous brands Covertan® and Novagryl® are still manufactured at the original site in Biesheim, France next to the Rhine.

Fiberweb have a dedicated and highly experienced agricultural division who look after all their agricultural production, supplying over 58 countries worldwide.

Unlike many other nonwoven producers Fiberweb extrude, convert, and join their fleece on the same site using the latest technology including high speed camera detection to ensure that their fleece remains the no. 1 brand for quality, strength and reliability.

Covertan is the original brand that Fiberweb first made nearly 30 years ago. It has the thickest fibres of any fleece made in the world which gives it its unique strength and reliability year on year.

Novagryl is a unique 3 layer fleece which is made using very fine fibre. This gives it a much softer feel, improved thermal properties and market leading elongation which allows this fleece to stretch to over 60% of its original width making it ideal for tall crops such as sweetcorn.

We carry a large range of fleece in stock but most of our fleece is made to order for each customer.

Lead times vary from 2 to 6 weeks depending on time of year.

For spring deliveries it is best to place any orders before Christmas to ensure delivery is made on time.

Fleece should be laid directly on top of the crop and secured with soil or sandbags. It must be laid as tight as a bed sheet otherwise it will catch the wind and flap damaging the emerging crop. A good quality fleece has 20 – 30% stretch so it can expand as the crop grows.

If securing with soil it is important not to use too much soil otherwise the fleece will be very hard to remove.

Fleece can be left on the crop as long as required but it is normally advisable to take it off in June otherwise the crop below will start to suffer from heat stress.

To remove the fleece simply pull out the edges and it can then be rolled up with a crop cover rolling machine and reused the following season if it is still in good condition.

Fleece is a relatively low cost crop cover which can be re-used for a second season if carefully handled.

It will advance certain crops by up to 4 weeks.

It will help protect early crops from frost.

It is possible to spray and irrigate the crop without having to remove the fleece. However, if spraying with sulphur or chlorine based products, this can damage the UV resistance and significantly reduce the lifetime of the fleece. Following such treatments, no claims can be accepted.

It will offer protection from wind, rain, frost, birds and insects. Because it is a light weight cover and the fact that it has to be removed during the summer it is not ideal for insect protection. It has been designed as a thermal crop cover to advance harvest dates and protect crops from frost.
