How to identify the occurrence of harmful changes in the soil quality?
What is the basis to make the management of the soil quality?
What is the soil quality?
“It is the capacity of a soil to
function continuously as a vital
system, within the limits
associated to its use, supporting
the biological productivity,
promoting the quality of water
and maintaining the health of
human and of the environment”
Doran and Safely, 1997
“Capacity of the soil to perform its function in
the current moment and the preservation of
its functions for future use”
USDA, 2008
Legal regulations of soil quality protection and management
of contaminated areas
Brazil (federal) - Resolution CONAMA 420/2009
Art. 3 - The protection of the soil must be made in a
preventive way, to guarantee the maintenance of its
functionality or, in a corrective way, to restore its quality or
recover it in a way compatible with the uses.
São Paulo State – Law 3.577/2009 (Decree 59.253/2013 –
regulated this law)
Art. 3 - Any individual or legal person that, by action or
omission, may contaminate the soil must take the necessary
measures to prevent any significant and harmful changes to
the soil functions.

Of Prevention and Control of Soil Quality
Art. 13. Aiming to prevent and control the soil quality the
businesses that develop activities with CONTAMINATION
POTENTIAL for soil and groundwater, at the discretion of the
proper environmental organ, must:
I – implement monitoring program for soil and groundwater
quality in the area of the business and, when necessary, in its
vicinity and in superficial waters;
II - present conclusive technical report about the quality of
the soil and groundwater, at each request for renewal of
license and prior to the end of the activities.
RESOLUTION CONAMA 420/2009 (Brazil)
Decree 59.263/2013 (São Paulo) – Regulation of Law 13.577/2009
Chapter II – of the prevention and control of the contamination
Art. 17. CETESB may demand from the legal responsible person for the
areas with potential sources of soil and groundwater contamination the
maintenance of a monitoring program for the area and its vicinity.
§ 1 For the following activities the MONITORING must be required by
CETESB:
1. In the areas with contamination potential (AP) where there is the
discharge of effluents or waste on the soil as part of treatment or final
disposition systems;
2. In the areas with contamination potential (AP) where there is the use of
halogenated solvents;
3. In the areas with contamination potential (AP) where there is the
secondary melting or recovery of lead or mercury.

APPLICATION OF SLUDGE AND EFFLUENT ON THE SOIL
When the application on soils is
acceptable?
The soil and the groundwater are natural resources to be protected and, therefore, the application of sludge or effluent on the soil must meet the conditions:
There is an agronomic benefit
Will not cause degradation and contamination of
the soils and
Will not cause contamination of the groundwater
The use of an area for pure discharge of effluents or
solid waste is not acceptable, even if there are no
receiving water bodies with capacity to receive
effluents, even if treated, in the area.
APPLICATION OF SLUDGE AND EFFLUENT ON THE SOIL
What if the application of sludge and effluents in agricultural
soil is not well executed?

Resolution CONAMA 375/2006 – Sludge of urban wastewater treatment plant (Annex 1 – Resolution 380/2006)
Regulations for the application of sludges and effluents on

Viability of the application
• Characteristics of the effluents and waste (organic,
inorganic substances and pathogenic agents).
• Characteristics of the areas of application
(granulometry, fertility and soil quality).
• Vulnerability and quality of the groundwater.
• Crop.
• Project and Rate of application
• Index pluviometric.
Present as requested by the Norms
Assess the viability of the continuity of the application
MONITORING PLAN
• Effluents and sludges – specific limits by the Norm
• Soil – limits are the Prevention Values (VP)
• Groundwater – limits are the Intervention Values (VI) and
for Nitrate = 5 mg/L
Salinization and Sodification of the soil.
Chemical and biological contamination of the soil.
(metals, organic substances, pathogens) .
Risk of contamination of surface or groundwater
(metals, organic substances, salts and nitrate).
Risks of the application
The increase of soluble salts in a soil
reduces the osmotic potential
The increase of the relative proportion of
sodium to other cations (K, Ca and Mg)
Dispersion of the clays and organic
matter
Salinization and Sodification of Soil
Limit values adopted in the CETESB Norms:
PST = Na+/ CTC= < 6 %
K+/ CTC = < 5 %
The application of effluents and sludges in areas that present soil concentrations of substances above the VP and VI agricultural is not permitted.

CEC = Cationic exchange Capacity (mmolc/dm3);
ks = concentration of potassium in the soil, expressed in cmolc/dm3, at the
depth of 0 to 0.80 meters
3744 = constant to transform the results of the analysis of fertility, of cmolc/dm3
or meq/100cm3 for kg of potassium in 01 (one) hectare for the layer of 0 to
0.80 m of depth
185 = mass, in kg, of K2O extracted by the culture per hectare, per cut.
kvi = concentration of potassium in the stillage, expressed in kg of K2O/m3

The results of the studies carried out by the Sugar and
Ethanol Industry
Assays with 4 different doses of stillage in 2 areas of sandy soils (area with
30 years of application of stillage and area without previous application):
Dose 1 = 0 (control) without applying stillage Dose 2 = Half the equation;
Dose 3 = equation and Dose 4 = double
• The agricultural improvement was 70 and 80% (1th year) and 42 and
152% (2th year).
• The radicular system has not reached 80 cm, as expected, but it was
denser.
• There was no increase in the pH and the organic matter in the soil, only
temporary change.
• The removed biomass of sugarcane 26 and 48% (1th year) and 50 and
63% (2th year) of K in the soil.
• Maturation (Pol% cane) changed negatively. The less harmful dose was
the Norm.
• The potassium went deeper in the soil profile, centering in the layer of
40-60 cm – lixiviating quickly with the first rains.
• Sulfate increased in all depths.
The recommended dose by the norm does not affect the soils (2 years
of monitoring).
• The productivity of the area without the stillage application (control) is
equal to the area with 30 years of application that received the dosis of
the Norm.
• The potassium not extracted by the culture tends to concentrate in the
soil and migrate in depth (lixiviation).
• Analysis of soil extract indicate lixiviation of nitrate and ammonium in the
first rain.
• The quarterly monitoring of the groundwater in the area with the
application of 30 years showed an increase of Ca, K, Cl and SO4 in the
groundwater. In this area the concentration of nitrates was greater than
the drinking water standard, even in the wells situated above.
• In the area without the application of stillage the monitoring wells were
dry most of the time, which affected the assessment of the impact of the
stillage application in groundwater.
