Positive Agronomical Test Results of KP Fértil® on Sugarcane
Harvest Minerals Limited, the AIM listed remineraliser producer, is pleased to announce positive agronomic test results for sugarcane plantation areas using KP Fértil®, Harvest's direct application natural remineraliser produced at the Company's 100% owned Arapua Fertiliser Project in
· Agronomic tests using KP Fértil® have returned superior yield performance in sugarcane plantation areas compared to the more traditional and widely used reactive phosphate Bayóvar fertiliser
· The higher the doses of KP Fértil®, the higher the yields presented
· The yields using KP Fértil® were also significantly higher when compared to that of an area with a control treatment without phosphorus application
· Tests were conducted under the leadership of Dr.
"Looking at the new market opportunity,
The agronomic experiments were installed in March and
Both field trials intended to evaluate the yield of sugarcane as a function of phosphorus ('P') doses (in kg ha-1 of P2O5) sourced from two different products:
1. the remineraliser KP Fértil® (3.2% total P2O5), and,
2. the reactive phosphate of Bayóvar (29% total P2O5).
The treatments consisted of three doses of 80kg, 160kg and 320kg per ha-1 of P2O5 for both KP Fértil® and Bayóvar, with each applied over the selected areas in both sugar mills. A control treatment area without phosphorus application was also tested, with 4 repetitions.
The application of both P sources occurred after the planting of sugarcane. Following the first sugarcane harvest, the yield performance was assessed based on three parameters:
1. total of stalk per hectare (TSH);
2. tonnes of sucrose ("POL") per hectare (TPH), and;
3. total recoverable sugar (TRS).
According to the summary of the analysis as seen in the charts below, the application of KP Fértil® returned superior yields related to all three TSH, TPH and TRS parameters analysed, compared to the application of Bayóvar at both rates of 160kg and 320kg per ha-1 of P2O5, the latter in general returned a decreasing yield rate performance as the doses were higher.
In conclusion, the tests have shown that the higher the doses of KP Fértil®, the higher the yields. The yields using KP Fértil® were also significantly higher when compared to the control area that had no phosphorus application.
The tests were conducted under the leadership of Dr.

Similar to the results found with the TSH analysis, KP Fértil® doses at a rate of 160kg and 320 kg ha-1 have also returned superior TPH results than the ones observed at same rate with the application of Bayóvar in both Santo Ângelo Sugar and

Harvest Minerals Limited (HMI.L) is an AIM-quoted low-cost and high margin Brazilian remineraliser producer, located in the heart of the largest and fastest growing fertiliser market in
The Company's product, KPFértil, is a registered and approved organic multi-nutrient direct application fertiliser. It contains many of the essential nutrients and minerals required by plants and, unlike most fertilisers, it does not require any complex processing or chemically alteration, instead it can be applied directly to crops.
KPFértil is produced at the wholly owned Arapua project, that consists of a fully permitted mine, production and storage facilities able to produce and deliver KPFértil to customers. Known mineralisation at the Project is expected to support 100+ years' production at 450Ktpa and to capitalize on this the Company has a dedicated in-country sales and marketing team with the skills, experience and contacts to sell KPFértil into the potential multi-Mtpa market on the doorstep of the Project.
