Shadenet - One big green ship in a sea of red!

In our long list of infrastructure development initiatives, shade net was an important one. Primarily because we needed an area to store the saplings which arrived almost 3-4 weeks before scheduled planting. Apart from storage of new saplings, we intend to raise a vegetable nursery within the structure. For now, we plan on sowing enough brinjal seedlings for about an acre on the field. Once we are done with this, we will try getting adventurous with some of the other exotic and not-so exotic veggies - just to prove the concept before scaling it up.
Following are some of the pictures of the shade net construction.

A total of 91 of these clamps were used for this structure measuring 120 ft by 60 ft. Distance between 2 successive poles was 10 ft.

Getting the structure intact..

A round of rotavator was performed before putting the fabric. (This was done to make the soil fine for the nursery)

Stretching the fabric..covering the top of the structure.Fabric was a mix of 50% and 35%. (35% means only 65% of sunlight penetrates through the roof)

Sewing up the corners..

A simple mix of cement mix, stones and sand was used to keep the base sturdy.

The sides need to be earthed up (about 8-10 inches high). This not only keeps the wall erect but also prevents rain water from entering inside.

Completed..

Coir Pith manure ready to use!

My previous post on coir pith manure was way back in April where I described the process of decomposing coir pith. Decomposition is extremely essential before it can be used as manure. In case you missed it, you can find the details here.

Well, the good news is that after making 150 beds of 500 Kg each and after almost 3+ months, the manure is ready. We  got it tested at TNAU and C:N ratio was 20:1 which is acceptable. According to our rough estimates, each bed is approx. 300 Kg (after decomposition). So there was a 40% reduction in mass during the decomposition  process.

Initially, we covered it with palm leaves. That was a management disaster since it was not easy to water the beds (sharp edges of leaves was a major hindrance) and was prone to shifting due to strong winds.
We figured it would be easier to use jute bags. This worked out great since we could water through it.

Ready to be transported to Melia Dubia pits...

The final product..According to academicians, you know it is ready when it is "coffee coloured".
In my opinion, it is better to get the C:N ratio tested to ascertain if it is ready to use.
