Home n’ Dry is the essential ingredient in Alkalage, Alkagrain, Alkastraw & Alkachaff. It is formulated as a mini pellet is from proven feed ingredients to aggressively release ammonia in the presence of minute amounts of moisture. This controlled release of ammonia is key to the preservation process. more->

Home n’ Dry is so effective at releasing ammonia it works on crops up to 90% dry matter, and begins to work within twenty minutes of coming in contact with moisture. Every 10Kgs of Home n’Dry added to a crop increases its protein content by 1.46% more->

Its main ingredients are urea and soya, plus a small percentage of other feed ingredients which help stabilise the pellet. The product contains naturally occurring enzymes which ensures 100% hydrolyzation of the urea.

There is never any urea left in Alka forages or concentrates.

It is supplied in 500Kg or 25Kg bags.

Home n’ Dry is applied at 40kgs / tonne, fresh. Weight of the forage, to uncompacted layers of no more than 30cm (1ft) deep.

Illustration 1Illustration 2Home n’ Dry is both safer and more effective than liquid or prilled urea as an ammonia releasing agent.

Straight urea whole crop and urea moist grain treatments rely on fermentation acids to breakdown the urea. The process is unreliable and can be dangerous.

Feedstuffs treated with straight urea often contain unhydrolysed material; whereas those treated with Home n’Dry, never contain any urea at feed-out.


Additive effect 80%-DM

The table opposite shows how efficient Home n’Dry is at releasing ammonia.

The Home n’Dry treatment and the straight liquid and prilled products (L urea & P urea) all started with the same urea content. However, the straight products only converted about half of their composition to ammonia. Home n’ Dry is both safer and more effective than liquid or prilled urea as an ammonia releasing agent.

The natural process is very inefficient,especially soat high dry matters,and consequently the straight urea application rate needs to be much higher than with Home n’Dry.

Remember, there is never any urea left in a clamp treated with Home n’Dry and its extra cost is recovered at feed-out. more->

It can be applied by a spreader at the clamp or tipped over flattened out loads. How it’s applied doesn’t matter, as long as the pellets are mixed correctly & evenly throughout the pit. more->

Ammonia gas permeates throughout the clamp and inhibits spoilage organisms. It also breaks down the bonds between the lignin and cell wall components to enhance the digestibility of the straw faction. Residual ammonia then re-combines with moisture and carbon dioxide to form ammonium salts, mainly ammonium bicarbonate. Ammonium bicarb is an excellent rumen buffer and nitrogen source. Occasionally it can be seen as white crystals under the sheet.

Another feature of the Home n’Dry preservation system is that it is additive. There are no measurable in silo dry matter losses with the technology, unlike the 5-15% DM forfeit sustained with fermentation processes. This benefit coupled to the Alkalage system’s mature harvest window always ensures optimum outputs per acre. Data from trial work in 2003, recorded a significant 15%dry matter feed-out advantage with the Alkalage system, compared to fermented wholecrop. more->



Alkagrains can be conserved in simple clamps when using Home n’Dry. No specialist drying or storage equipment is needed.

Home n’Dry pellets are added at a minimum of 30Kg/tonne to 15-20% moisture grain, though wetter grains can be conserved with higher volumes of pellets.more->

All cereals are suitable for Alkagrain production, including wheat, barley, oats, maize and sorghum.

Grains can be stored whole and rolled or crimped as needed, or they can be processed and clamped at harvest. Grains must be well damaged for complete digestion but not floured. There has to be some structure within a clamp so the ammonia gas can permeate through all its contents. Moist grains specifically must not be over consolidated.

Alkagrain Maize can be produced from relatively immature Maize Grain. This seems possible because of the relatively small amount of sugar in Maize and the larger grain particle size. However a number of additional precautions are necessary to ensure success. Alkagrain production- For Moist Maize Grain





As with Alkalage production it doesn’t matter how the Home n’Dry pellets are incorporated with the grains, as long as they are mixed thoroughly and accurately.

They can be mixed with a loader bucket on a clean hard standing or through a feeder wagon.

Both crimpers and roller mills are suitable for damaging grains but a forage harvester fitted with an integral small grain cereal processor is the quickest method and achieves optimum results. In the picture below the Class 970 forager can effortlessly process 50 tonnes of pre-treated grain / hour with one engine at 1800rpm. In reality the only limitation to processing large volumes of Alkagrains in this way is feeding the beast.

Features and benefits of ammonia & Home n’Dry in conserving feed-stuffs.

Ammonia’s anti-microbial action prevents fermentation, destroys moulds and denatures mycotoxins. In effect it sterilises and cleans the crop making it stable in storage even after exposure to air at the face. Treated crops can be safely moved and restored.

Ammonia further combines with water and other components in the crop to make stable ammonia salts – mainly Ammonium Bicarbonate.



This creates an Alkaline buffering environment,(High pH usually in excess of 8.5), which means that both in the mixer wagon and in the rumen, Acid Loading is improved.

This in turn improves digestive efficiency and feed intakes.

Increased feed intakes and stabilised rumens improve both animal performance (milk yield or gain) and health (less digestive upset, better feet, better body condition, better milk quality etc)

Ammonia increases fibre digestion in the stored materials as it reacts with the acidic and indigestible lignin components in the plant fibre structures.

Home n’Dry is made from feed ingredients – mainly full fat soya and feeding grade urea. The pellets are highly nutritious in their own right and are a concentrated source of Protein with the following analysis.

Dry Matter           97%

Crude Protein       146%

Oil                        9%

Fibre                     8%

Simple arithmetic tells us that adding each 10 kg of Home n Dry will add over 1.4% protein units to the end product.

Typical application rates are 30 to 40 kg per tonne, which therefore adds protein content to the finished material of 4.2 to 5.6% protein units. Home n’ Dry Pellets are a very valuable and cost effective addition to the diet.

In effect we are “Using feed components that need to be bought anyway to balance the diet to preserve and stabilise the feeds at harvest. The full feed value is recovered at feedout”

Home n’ Dry Pellets can be used to stabilise and preserve any feed ingredient that is relatively low in moisture and low in sugar. Main applications are in mature cereal whole crops – Alkalage, cereal grains – Alkagrain and cereal straws – Alkastraw. However as a simple robust technology it can be used in a wide range of specialist applications.

The success of the Home n’ Dry based preservation system lies in the fact that it effectively conserves materials

Without Drying so saving energy and energy cost.

Without Fermentation so eliminating fermentation losses that amount to at least 10% of the dry matter in all fermented crops. more->
