The best way to have a great garden is to grow roots. As roots break down in your soil it then creates organic matter and higher pH. High level of organic matter gives you higher soil temperatures which are then less prone to fluctuation. This promotes healthy plant growth. Compare a long term vegetable patch against a short term vegetable patch, or even just the sandy soils of Perth. The long term vegetable patch will most likely have an organic matter of 6–7. The short term vegetable patch will more likely have a level of 1. A long term vegetable patch would have had scraps and mulch thrown on it. The scraps/mulch has slowly broken down to create new organic matter and ultimately a better pH level.
This is great but only if rot is happening. What’s needed to help production of organic matter is fungi/microbiology. Without the fungi, roots and such from older plants will just sit on the surface, the nitrogen goes upward into the air and no benefit will be gained. If you have high organic matter in your soil, the fungi in the soil will break down the roots and turn it into organic matter. In effect – recycling the plant. This is the beauty of pig poo. It already contains fungi.
Pig poo itself contains organic nitrogen, potassium and phosphorous. It also includes manganese, zinc, sulphur and calcium. Calcium is very important for plant health, i.e. vegetables, fruit. If calcium levels are too low then their shelf life is short. The pig poo has high levels of calcium so your vegetables will keep longer.
One of the reasons your garden will love the pig poo is because it’s nutrients are organic in nature. Phosphorus in particular is available as a non-acid based P. In laymen’s terms nitrogen and phosphorus are being accessed by your plant in a neutral environment.
