While Lute Larson may have developed additional rates, she started with the same that I have access to, but have not has occasion to use, in the case of Hard Pan. Hard Pan either indicates the lower point of tillage and is some times treated by the sue of irregular depth tines or chisel plough. It usually is associated with clay or some form a colloidal. It may be related to loading by stock or machinery, again related to a clay layer. One can not create a hard pan in sand, gravel or loam. The advantage of using Gypsum, in some places called Clay Breaker or Pan Breaker, is that it is a very low impact, energetic method, which requires little fuel/ machinery and does not bring salt or clay to the surface, nor does it bury the soil in the lower levels. As I have said before, there is nothing like a fully functional BD cycle to assist. A good organic cycle will also work, but I see a BD cycle as being better. In a Chemical Cycle, most activity is in the top 50 mil (2") or so. A really high firing Organic or BD Cycle can penetrate 400, 500 or even 600 mil. This will require enough soil biota food, as stated in the earlier post, and mineral balancing, if required. In cases of bad pan, gypsum will bring results in months instead of years. The amount of gypsum held in the space made by cupping both hands and spread on a square metre is about one tonne to the hectare and is the minimum amount. If one has half a metre to one and a half metres to deal with, to get down to weathered granite and to allow in ground drainage, such as in totally saturated soils, then, one may use up to four tonne to the hectare. This would not usually be applied at one time, but over two to four years. Over time the effect of the gypsum will fall away and on occasionally, need replication.
I have 50 mil to 150 mil of highly clayey top soil, with 100 to 150 mil of clayey sub-soil, with 600 to 1,200 mil of sticky brown clay, over a penetrable weathered granite of 700 to 1,500 mil, then solid granite. I have gone from drowning fruit trees and vines to allowing drainage, with the equivalent of around three tonne to the hectare over three years. This has been supported with composting/ Preps/ Soil Food. The roots can now get down to the natural mineral layers. I( have over come the difficulties related to the drying of clay soils, where there is great damage to the root hairs, which only shows up later as set back trees and is usually regarded as being something else. If your soils clump, clod or crack, you have to look at breaking them with gypsum.
When looking at this, do not get carried away with trying to work out the chemistry. We are dealing with energy and the various attractive forces at a molecular level. We still need some functional cationic forces to hold water and minerals for use by the soil biota and ultimately the plant, but we also need to allow penetration of air and water.

Clay has the ability to cling together and form tough blocks. Great for
making adobe or pise houses. Increased soil carbon and increased soil biota
will help, but in the short term use one to four tonnes of gypsum to the
hectare, will break the clay and allow water penetration and largely break
the pan without ripping. If you trench, you will most likely loose your soil
into the lower regions and bring the clay to the surface. It will also tend
to make a place for water to lay and rot the roots. I would not do it. Try
gypsum first.I don't have a lot of experience in this area being my bottom lands were never worked with tractors.
But I believe Lute Larson and others have had great Radionic success with hard pan and even standing water using Radionic rates to increase porosity and air circulation. The field broadcaster would be a great device to set these patterns consistently.On a slightly different tact I intent this coming year to pay closer attention to light circulation in soil.
Mark Purdey's work and discussions here on the list have touched on Light's relationship to to proper growth and mineral transmutation.Given my assumed role of CU & ZN in soil's circulation of light do you think that gypsum would decrease heavy clays tendencies to towards celating these metals.
Gypsum as a "gem" stone has interesting transmissions of laser light with odd effects ie halos and hot spots.In musing
