A-maize-ing




This week we planted our third biochar field trial - 1/2 hectare of yellow corn. The corn will be ready for harvest in 4 months providing us with relatively rapid results, in comparison with pineapple and plantain.

The biochar was ground to particles no larger than 1cm and the biochar-compost mixtures were pre-mixed and applied to the field in parcels, using the same methods as the pineapple field.

Cart Upgrades, Wood Waste Biochar, and Signs

Before












After

The biochar carts were in need of some repairs. The wire meshing intended to keep the biochar in each cart has deteriorated over time - which is no surprise considering we've completed over 100 burns at temperatures around 800C! The new design does not include wire meshing but rather metal posts that we hope will be able to resist the heat. 






We recently completed our first burn using waste wood. This biochar isn't ideal for planting crops for consumption, however we are sure we can find other uses for it. As seen in the bottom of the two photos, nails and other bits of metal remain even after burning.



Volunteers at Villa Carmen helped out the sustainable agriculture and biochar programs by making signs to identify biochar treatments in the field. These signs will hold up through the rainy season and make periodic measurements and harvest a breeze.

Plátano




In addition to planting 1/2 hectare of pina, we have also planted 1/2 hectare of plátano huayco. This variety of plátano is used for cooking and is ready to harvest in approximately 9 months. The plátano also received experimental applications of biochar and compost in a localized application (biochar/compost applied in each hole prior to planting). 





Plátano huayco contains more starch and less sugar than dessert bananas and therefore must be cooked prior to eating. In Peru, chips made from plantain are called chifles - below is a recipe to make your own!

Ingredients:

Green plantains (or green bananas)
Oil of choice for frying
Salt to taste
Optional: Aji (hot peppers), or garlic to flavor the oil

1. Peel green plantains or green bananas. Be careful as they tend to stain clothes and cutting boards. 

2. Slice plantains lengthwise (full or half), or as thin rounds or diagonal ovals. A mandolin is recommended for optimal thinness. 

3. Heat the oil, either in a deep saute pan or fryer. Ideal temperatures for frying is between 375-400 F. There should be enough oil in the pan to fully cover plantains. 

4. Add plantains to the hot oil, being careful not to overcrowd them or let them stick together. 

5. Fry until the chips are a golden color. 

6. Remove chips from oil and drain on a paper towel. 

7. Sprinkle with salt and serve either warm or cold!

12,000 Pineapples!




With the help of the Asociación de Piñeros we have successfully planted 1/2 hectare of pineapple - 12,000 plants!




Pineapple "seeds" are actually the crowns of pinapples. These seeds will send out roots in the next few weeks and will produce fruit in a year and a half. 





The 1/2 hectare pineapple field has been divided into experimental parcels. The experimental parcels received a constant application of biochar, with decreasing rates of compost.

Arrival of the Grinder

The arrival of the grinder was much anticipated. There’s a stockpile of biochar ready to be ground and the planting of experimental pinapple, plantain, and maize plots is right around the corner. The biochar can now but processed into uniform size making it both easier to apply and more effective in soils. Finely ground biochar increases the water retention and allows for worms and other microbiota to transport the material in all directions resulting in long-term improvement in soil quality.

The very first test run - success!
