NPK + biochar appears to increase yield when biochar makes nutrients available through plant roots and mycorrhizal hyphae, and when biochar reduces nutrient loss through leaching or other factors. The

Tomasco, When the orchard owners calculate their NPK do they do it based on the harvested yield. In this case, the yield would represent the nutrients mined from the soil. If not than the yield based

Mike, In response to your questions, I do not have additional information beyond what is in the reports. I believe they will be conducting additional trials this year, but do not know the parameters o

I think that Mike has hit on something important that seems to have been lost in all of the other calculations. Much resides in the ROI for the farmer and the cost/availability of biochar v. NPK. If y

Francesco, Do you know if the yield response to the chicken litter/biochar response was a good investment for the grower....? Were the plants direct seeded or planted as transplants.....? If were to r

Mike, I agree complete regarding the application rate. I will reach out to those involved in the research to see why they choose those rates and what they are planning for their present trials. Person

Francesco, The 2017 study used 8 tons of biochar per acre to acheive theirs results..... This size dose could be an economic and logistical challenge for many growers to execute WiTHIN season. it woul

Here are a couple of studies conducted by Univ of Washington on the San Juan Islands, WA a few years ago. It was a multi-year study. The first year measured the NPK retained by biochar enhanced soil v

Tomasco, In designing your NPK leaching mitigation experiment you may want to consider looking at a 2 season time span, as your experimental timeline. This 2 season look allows you to see which season

#fruit #orchard #leaching

Tomasco, What specific types of NPK are being used...? How and When are they applied...? Do these growers apply other macro- and micro- nutrients.in addition to NPK...? Are you tracking what the cost

Tomaso, Great questions. For experience in Australia see: https://www.agtrialswa.com.au/trial/productivity-gains-from-biologically-active-soil-initiated-through-biochar-activated-compost-in-an-avocado

Tomaso, Many biochar makers and users are taking a different approach from using biochar alone as the preferred soil amendment and are pre-charging the biochar with microbiota. This approach abandons

we are trying to plan an experiment in "industrial" pear and apple orchards we want to understand if and how much using biochar in the orchard would could reduce chemical fertilization (simplifying NP
