RECYCLING IN THE FARM
Magana Flowers (K) Ltd is committed to Environmental conservation and sustainability. There are initiatives put in place in the use, re-use and recycling of the scarce resources.
One of the ways of prudent water usage is Hydroponics technology. This is growing the crops under substrate other than soil.
The crops were originally grown under the soil when the farm started . However, the hydroponics started in early 2000. Currently the farm is 97% under hydroponics. Troughs are laid on raised beds and filled up with fine pumice and coarse pumice at the base to facilitate water drainage .
Double rows of driplines are laid across the bed to feed the crops planted in 2 rows across the bed. Out of the 100% of water pumped through the dripline, about 70% is used up by the crop and about 25%- 30% drains out. The 30 % drain out is collected in the recycle pond through a series of drain pipes.The recycled water is then passed through a channel for disinfection using chlorine doser.
The recycled water which has a low Ec is mixed with fresh solution at a given ratio and then pumped back to the field to feed the crops.
RAIN WATER HARVESTING
There are 8 water reservoirs (3 major and 5 small) with a total storage capacity of 160,000 m3.
All rain water collected from the roofs of main buildings and greenhouses is harvested on the gutters and down pipes and channeled to the main reservoirs. The rain water helps to reduce the amount of water extracted from the boreholes. The harvested rain water is used for Fertigation and feeding the crops and another portion used for showering inside the greenhouses .
Fingerlings were introduced in the main reservoirs and their population has continued to increase over time. This is a clear indicator that the water is clear from any aquatic pollution.
BORE HOLE WATER EXTRACTION
There are 6 active bore holes all registered under the Water Resources Management Authority (WARMA).
When the rains subside and the water levels go down, borehole water is extracted to top up the water reservoirs . A small portion undergoes chlorination treatment for domestic consumption by within the company premises and by staff who reside around the farm.
We are aware of our responsibility to the environment & undertake sustainable development such as drip irrigation, rainwater collection, water recycling, reforestation & re-fertigation.
100% of our irrigation water is recycled ensuring no chemicals are leached into the environment
Biological pest control methods minimize the use of harmful chemicals from within the farm.
Use of donkeys and carts to ferry goods in the farm hence reducing our carbon footprint
We have also planted indigenous trees all around the border of the farm. Around the farm blocks, some areas have been reserved for indigenous trees and forests. Where greenhouses cannot be built, animals and birds are encouraged to inhabit.
These are indigenous trees that were established/ planted since the farm commenced its operations 25 years ago to date with a majority of them planted in the year 2006. The forest occupies approximately 4 to 5 hectares of farm land. The forest is situated on the sloppy side of the farm prone to soil erosion and soil degradation.
A few of the trees along the boundary were planted at the onset of the farm but a majority were planted in the year 2006 as shown below;
|Kikuyu name||Common name||Botanical name|
|Muhugu||Silver oak||Branchylaena huillensis|
|Mukima||Silky oak||Gravellia robusta|
|Mwarobaini||Neem tree||Azadirachta indica|
|Muthiga||Kenya Green heart||Warbugia ugandensis|
|Muiri||Red stinkwood||Prunus africana|
The forest and bushes which are situated on the sloppy side of the farm has served in many positive ways of environment enhancement, in that it has;
- 1. Controlled erosion
- 2. Become wildlife habitat.(Birds)
- 3. Acts as a water catchment area
As there are no plans to use this area for any farming activity, it has been set aside as a conservation area. It acts as a buffer zone between Magana Flowers Kenya Limited, the river and the farming activity beyond it.
The conservation is compatible with sustainable agriculture in the sense that the bees are the agents of pollination without which certain plants which are not self-pollinating will be faced out. On the other hand beneficial insects like the lady bug are agents of integrated pest management and the conservation area is their natural breeding ground. Birds that depend on nectar will readily get it from wild flowers whose pollination has been assisted by the bees.
The forest is purely for the company though at times you could find outsiders picnicking out there especially from the Kikuyu side.
