sandy loam soil lacking clorophyll content
« on: June 06, 2020, 10:42:28 PM »
Hi fellas I've been trying all along to grow decent veggies on my sandy loam soil,however in the end my plants are growing compromised with lack of color and vigor.although I'm fertilizing with nitrogen fertilizers I haven't been able to achieve any greening action compared to my high clay soil.I've amending hydrated limestone and chicken manure before planting,I'm stumped though any ideas?

Try looking at some photos of common plant nutrient deficiency symptoms by the appearance of leaves. Could the soil be excessively acidic or alkaline? Though I've been to Trinidad I don't know much about your soils. There could just be an imbalance causing the problem, or some essential nutrient.

Maybe my nitrogen applications are being restricted due to excessive acidity (wack ph)

Yes, lots of nutrients get tied up in acid soil, and if low enough aluminum gets freed up to toxic levels.

You could do a simple experiment with wood ash that should help correct acidity and add some potssium.
Do it to one or several plants or grass and see it it helps green things up. You could also do a soil pH test.

Thanks alot bro,I've been having alot of disease pressure as well due to poor nutrient uptake . are there any other effective methods that can raise soil ph for plants that are already under cultivation?I've heard about caustic potash (potassium hydroxide).

The standard worldwide is lime, it was discussed in the link. As local cacao farmers about it I read that Trinidad has plenty of acidic soils.

Wood ash, or shells that are kiln baked (lime) will do a great job.
The finer the amendment is ground, the quicker the effect.
