Sewage Sludge Conditioning using Opuntia Ficus Indica Juice

This work aimed to study the possibility of using plant matter, Opuntia ficus indica juice (OFIJ), for conditioning the Beni-Messous (Algiers) wastewater treatment plant sludge. The optimum dosage of OFIJ was found to be 0.4 g×kg-1 of dry matter, for which the residual turbidity, the dryness of the filtration cake, and the specific resistance of filtration were found to be 2.5 NTU, 24% and 0.13×1012 m×kg-1, respectively.

Effect of supplementation by cactus on female goats

The objective of this study is to investigate the effect of barley substitution by cactus during pre-mating phase on some reproductive parameters and blood metabolites of goats.
Forty adult goats of local breed were allocated to two groups based on live their weight. Each goat of both groups received 0.9 kg of barley straw. Goats on concentrate group (CC) received in addition 425g/goats/day of a concentrate (mixture of 80% barley and 20% soybean). Goats in the cactus group (CAC) received 256g of a concentrate (mixture of 68% barley and 32% soybean) and 2600g of cactus pads. Feeding regimes were applied on the average for one sexual cycle before mating and continued until 5 weeks after.

Gate post part one

Today saw the installation of a telephone pole that will serve as a gate post. It's on the north end of the entrance, pictures below. 

I surveyed the cactus field and found that about 70% of the surviving pads are budding out. This is amazing in light of the damage they sustained.  No visible intrusions of the electrified perimeter either. 

Tomatoes and onions got planted today after some additional rototilling in the backyard.
