STIMGRO HYBRID FERTILISERS

Introduction
The concept of availing in this market and beyond a hybrid fertilizer that combines both inorganic or mineral fertilizers and organic fertilizers or manure cannot be over emphasized. Using pelleting technology we have been able to make a break through in fertilization management systems in Kenya and beyond. The development of site specific or ecozone specific fertilizer recommendations are not available. These are issues that are adequately addressed by our products. We can formulate different fertiliser compositions based on the following regimes.
• Crop specific
• Soil specific or ecozone specific
• Farm specific

Integrated soil fertility management (ISFM) involves the use of carefully calculated combinations of mineral and organic fertilizers in association with complementary crop practices such as tillage, rotation, and moisture conservation. The broad aim of ISFM is to utilize available organic and inorganic sources of nutrients in a judicious and efficient manner. Optimal nutrient cycling is essential, the aim being to create a tight system that synchronizes the release of nutrients by the soil with the demand by the crop. At the same time, the system seeks to minimize nutrients losses that would occur through leaching, soil erosion, runoff, volatilization and immobilization.

BACKGROUND INFORMATION
Soil fertility is the capacity of the soil to support the growth of plants on a sustained basis, yielding quantities of expected products that are close to the known potential. Such productive capacity requires the provision of adequate and therefore adequate growth, production and yield.
Some of these are soil moisture and temperature, aeration, water holding capacity, a pH that should be near neutral,
an absence of hardpans that otherwise would inhibit root growth, adequate organic matter, and other conditions that
promote the growth of soil micro-organisms.
The recognized forms of soil degradation are erosion, physical, chemical and biological soil degradation, salinization
and pollution. Chemical degradation includes salinization, sodication, acidification and the depletion of plant nutrient
content in the soil. Biological degradation is loss of soil organic matter and soil biodiversity. It influences both soil
physical
properties and nutrients. All these forms of degradation lead to a lowering of soil fertility and land productivity. Farmers
get less and less from the same area of land, or yields have stagnated at very low levels. This problem is now recognized
as being one of the major contributors to the persistent food deficits and high poverty levels in the eastern Africa region.
It is estimated that countries in the region need to increase agricultural production at least threefold within a generation.
This level of increase is required to eliminate the current deficits, allow for better nutrition, obtain a significant
marketable surplus to improve cash incomes, and to accommodate additional demand created by the growing
population. Because of low production at the farm level, the majority of the people in the eastern Africa region live below
the poverty line
(that is, on one US dollar per person per day according to World Bank Standards). With these exceedingly low incomes,
they are unable to afford the very basic needs of food, clean water, health services, proper shelter and education.

Some of the main causes of poor productivity are,

• Declining plant nutrient status
• Very little use of organic and inorganic fertilizers
• Lack of attention to soil acidity
• Poor conservation and management
• Poor tillage practices
• Tree growing is not focused on the improvement of soil fertility
• Excessive soil erosion by water and wind.
• Land Fragmentation
• Poor land-use planning
• Land tenure problems
• Inadequate extension services and infrastructure
Justification
Inorganic fertilizers are a normal requirement for high crop yields. It is estimated that 30-50 % of today’s crop production in the world comes directly from the use of inorganic fertilizers. Use of the correct type, rate, time and method of application of fertilizers is important for raising production and avoiding damage to the environment. Inorganic fertilisers can quickly replenish lost plant nutrients. However, despite several years of agronomic research on the response of specific food crops to various types of fertilizers, the results on there suitability are over generalized and have rigid recommendations on their use. Furthermore, continued use of inorganic fertilizers without inputs of organic matter can lead to declining yields because of other problems such as imbalance or deficiency of certain nutrients, acidification of the soil or deterioration in soil structure. Inorganic fertilizers should not be considered as an alternative to organic fertilisers or a substitute for organic inputs.

They have complementary roles.
Smallholder farmers are unable to significantly raise production using only the organic manures available locally. There is poor biomass production (because of low soil fertility and often inadequate rainfall), and therefore little availability of organic materials for composting or for direct incorporation into the soils. The rate of accumulation of soil organic matter is also reduced by the very rapid mineralization that occurs in the prevailing hot climates. Termites also consume much of the organic matter, especially in semi-arid areas.Competition between uses prevents the accumulation of organic matter in the soil.

Most crop stover is removed from the farm as livestock fodder. Animal manures are often not returned to the originating farm. This combines with continuous cropping to cause serious soil mining and fertility decline.Land productivity must be raised drastically and rapidly to stem the worsening rural poverty that results from declining yields. This will require significant increases in the use of organic and inorganic fertilizers.Extensive research carried out in this area by KARI and other institutions on manure application and mineral fertiliser application has resulted in the conclusion that a combination of manure and mineral fertiliser give better yield hencefinancial returns than either of the two alone. More so where there is irrigation or where adequate and well distributed rainfall is available a combination of manure and mineral fertilisers significantly increase yields.

The question of adoption of hybrid seed varieties and accrued seed potential being achieved in the yields, whereas many
farmers realising only a fraction of the productivity gains from adoption of these seeds is an area we intend to explore
vigorously to ascertain that soil conditioning from manure is agronomically important and a major requirement for high
production. The misconception that hybrid seed will yield to its potential in poor soils whether mineral fertilised or not
need to be addressed.

THE CONCEPT
Manure is agronomically necessary for crop production due to its unique role of not only fertilising the soil but more so conditioning the soil. Using pelleting technology the new active component namely manure can now be used as a unique transport vehicle for different soil applications and a variable tool to enhance management of diverse, difficult and unavailable soil applications especially for field crops. Like the now famous drip system technology using fertigation where water is the transport vehicle,a cocktail of different fertilisers are mixed depending on the soil analysis and crop requirement.
Our technology tries to translate the same to rainfed agriculture which has enormous challenges for optimal production. This is a our novel and original concept and, we are calling it FERTIMANUGATE.
