Hi,
JS cannot reduce soil pH.
Instead, use JMS microorganism solution.
Regular application of JMS balances soil pH by restoring balance of microorganisms and balance of nutrients in soil.
In empty fields prior to planting, JMS can be sprayed on soil undiluted right before heavy rain.
If crops are already planted, JMS has to be diluted with water at least 10 times.
20-100x dilution s is what JADAM farmers usually opt for.
Apply JMS with a lot of water so it can reach deep into soil.
If using drip irrigation or sprinklers to water plants, irrigate diluted JMS for about 15-20 minutes or apply at least 3 liters of mixture to every square meter of soil.
Before planting, apply JMS deep into soil 4 times every 5–10 days.
Then after planting, drench soil with diluted JMS every 7–10 days until harvest.
