Should not Filipino farmers learn from India, where the rotavator is now the most used implement for farming? ANN says (Author Not Named, 16 Aug 2023, “Why Rotavator Is The Most Used Implement For Farming In India?” Tractor Karvan, tractorkarvan.com). And so we go to India and read “Why Some Inferior Technologies Succeed? Examining The Diffusion And Impacts Of Rotavator Tillage In Nepal Terai” authored by G Paudel, V Krishna, A McDonald & Vijesh Vijaya Krishna (Ideas, ideas.repec.org).

G Paudel et al say:
Rotavator is a tractor-operated cultivating implement for
shallow tillage, which operates by pulverizing soil with the help of rotating L
or J -shaped blades. Rotavator tillage has been spreading rapidly in many parts
of South Asia, despite having a large body of evidence on its negative
consequences on soil quality and crop yield from the experimental research
trials.
Ah! I Filipino agriculturist – BSA major in Ag Edu 1965, UP
Los Baños; 2001-2008 Editor In Chief of the Philippine
Journal of Crop Science (PJCS) – I believe G Paudel et al when they say
that on rotavator tillage, the evidence is that it has “negative consequences
on soil quality and crop yield.”
More than 5 years ago, 26 March 2018, I wrote “Organic
Farming & The Lesson Of The Rotavator: How To Feed The World” (Organic Country, blogspot.com),
where I quote Tania Lewis & Emily
Potter describing Edward
Faulkner’s concept thus (books.google.com.ph):
Faulkner's conception of trash farming saw soil as a
living system of capillaries. When conventional plows are used, the soil mass
is violently broken apart, disrupting the capillary connections through which
water seeps. Faulkner's answer was taken from Asian farming practices.
Eschewing the plough, he recommended disc-rotoring the crop residue, or trash,
into the soil. The result was a "trashy" surface soil scattered with
debris and "teeming with organic matter" (Beeman 1992: 96).
Today,
when farmers in India, the Philippines and US of A operate the rotavator, they fail
to create a trashy surface and instead destroy the
structure of the soil and not enrich it!
If
operated like I know how, the rotavator creates that trash mulch over the soil
surface automatically. That is why I am writing this to attract any investor –
I’m looking at the PH hybrid rice companies – for us to reinvent the rotavator
so that it cuts the soil and produce the trash mulch (soil & weeds cut
& mixed) automatically and spread that material all over the field
automatically! The automatic “Organic Rotavator” I call it.
I
am thinking of some PhP2 million to produce that reinvented rotavator, with
techno demos done in Luzon, the Visayas, and Mindanao. I’m calling on Bayer AG, LongPing, Pioneer Hybrid, SL Agritech
and Syngenta, any or all of them
coming together, to support the project I now call “Automatic Organic
Rotavator” where even a novice farmer or non-farmer can operate the machine and
still automatically produce a trash mulch all
over and immediately begin to fertilize the
whole field! Any takers?@517
