A cricketer turns his again on the enjoyment of professional sports activities to consider on a total new challenge: farming devoid of soil.
Yasser Parker considered he experienced fulfilled his childhood aspiration by turning out to be a specialist cricket player. He relished his times in front of the crowds, actively playing a sport that even took him abroad. Then, seven years into his chosen career, the potential commenced to glance less rosy.
“In my closing year, I went to the Uk to participate in a year at Stratford-on-Avon cricket club that is when it dawned on me that monetarily, I was not going to be equipped to get where by I want to be,” 30-12 months-old Parker recalled.
It was time for a new challenge.
A pay a visit to to a modest three-acre plot in Marondera, a farming city 90 kilometres from Zimbabwe’s cash, Harare, today displays a new, thriving, operation and a entirely distinct everyday living. Parker’s resolution to his challenge? Aquaponics.
Aquaponics is a mixture of fish farming (aquaculture) and hydroponics, a farming method exactly where vegetation are developed without the need of soil.
“We bring collectively fish farming and hydroponics. We use fish squander to mature our crops,” Parker spelled out as he showed off his procedure.
“Another way to glance at it is that the fish deliver fertiliser for our vegetation, and our plants purify the drinking water for the fish it is a symbiotic romantic relationship,” he included.
For Parker, the journey from cricket to getting a person of the very first farmers to experiment with aquaponics is a circumstance of sheer coincidence and curiosity.
“I did my significant school at Prince Edward Superior School in Harare but did not do so nicely I managed to go four O-stage topics, maths not included,” Parker mentioned. In Zimbabwe, five Common-level topics are thought of the acceptable minimum for educational development.
“I moved to Prestige to check out and move 5 O-Degrees which I did not get,” he ongoing.
“My mom gave me a decision, she desired me to go to Gwebi Agricultural School, but I determined to choose up cricket,” Parker added.
Acquiring hit a wall in his cricketing vocation, Parker returned to Zimbabwe with out a apparent prepare of how he was to commence.
“I sat all-around for about six months to determine out what I wished to do I did a carpentry training course at Harare Polytechnic College and inevitably settled for farming,” Parker spelled out.
Parker was at first drawn to fish farming but data that he located on the online inspired a different idea.
“We were being intended to do fish farming on this plot, but 1 working day I was on YouTube and stumbled upon aquaponics. I did research and realised that this is some thing I could do – and begun the set up,” Parker stated.
“Finances at the time had been a little bit tricky, despite the fact that three weeks into our improvement, some investors came and supported the challenge,” he included.
Devoid of a qualifications in farming, aquaponics for Parker truly represented a simpler choice than frequent farming. From his study he realised that thriving classic farming expected coming to terms with sophisticated challenges like the soil evaluation, irrigation, fertilisers and weed manage needed in normal farming. That was if he could locate more than enough land. And then, there were being threats owing to climate ailments, specifically without the need of access to a water supply for irrigation.
Aquaponics, though more pricey to finance in the beginning, presented an answer to a lot of of people issues.
“You can set it up wherever, and it can be any measurement – from anything for property use in your backyard of 40 sq. metres to a thing you see in this article, of 2,500 square metres. You can improve anything at all you have to have to survive in phrases of refreshing deliver and protein. Fresh new develop remaining the plants and protein coming from the fish,” Parker discussed.
Zimbabwe’s little-scale farmers have long faced difficulties because of to the rain-fed variety of agriculture they go after and this period, a lot of farmers have been remaining counting losses owing to an erratic wet year. Parker believes if these difficulties persist, aquaponics could be regarded as a alternative.
“In conditions of sustainability, we use 90% fewer water all the drinking water in the procedure is recycled,” he explained.
“We really don’t have to dump any h2o at any time the only h2o that we eliminate is by way of transpiration and evaporation. It is very unique from your traditional farming approaches with the soil,” he additional.
Parker has only one everlasting staff at his operation. He only employs everyday personnel all through the harvest year.
“The day commonly begins at 5:30 I scout to make guaranteed plants are not obtaining attacked by pests or conditions. Right after that, I acquire readings of the PH and temperature drinking water parameters,” Parker reported.
Frequent exams in h2o excellent are intended to ensure the ailments – or drinking water parameters – remain conducive for fish farming. Variables checked consist of temperature, dissolved oxygen, alkalinity, hardness, ammonia, and nitrates.
Even though hardness and alkalinity do not transform frequently, oxygen and PH fluctuate and have to be periodically checked failure to do so can result in the fish dying.

The fish are fed twice a day, from 6 am to 10 am, then between 4 pm and 5.30 pm in the late afternoon.
Describing the system, Parker stated the aquaponics technique brings together a fish farm and a horticulture farm, with h2o staying the connecting ingredient.
The water that supplies habitat to the fish will become rich in vitamins about time from squander excreted by the fish that water is then fed to the horticulture aspect, wherever the crops endure entirely on the residue water – with out soil.
As plants absorb vitamins via organic organic filtration, they thoroughly clean the drinking water, and it is fed back to the fish in a cyclical fashion.
The plants count on the fish to deliver waste, although the fish want the plants to purify the drinking water.
Periodically, there is a cleaning procedure which is completed to filter out the squander that crops would have unsuccessful to soak up.
“We drain our filters the moment a week and ship them into a mineralisation tank, where we feed the naturally happening bacterias with molasses and the micro organism split down that good fish waste, and it is an enriched fertiliser again in the system,” Parker defined.
According to Parker, even if he is given a far more important piece of land than he at the moment occupies, soil farming is out of the issue since aquaponics is a lot more successful and environmentally welcoming.
“I was captivated to the sustainability factor I have been adhering to the global crisis because I was young. We are 10 moments much more effective for each sq. metre applying this variety of farming than farming in the soil,” Parker claimed.
“For instance, for each acre, we will expand 120,000 heads of lettuce ten instances a yr and appear up with 1.2 million heads of lettuce whereas, in the soil, from what I have study and what I have been instructed, you are doing 40,000 for each acre and you are harvesting a few periods a yr. It was a no-brainer,” he adds.
Parker, who promises he is the to start with to established up a semi-industrial aquaponics procedure in Zimbabwe, admits that the price tag outlay could be limiting for some unless of course there are traders.
“If you are going to be environment up a hectare, it can be from 400,000 dollars to 1.6 million, relying on how substantial-tech you want to go.”
In accordance to Parker, the beauty of greenhouse farming is that one can mechanise and automate pretty much every thing. A person can go as automated as setting up temperature and humidity sensors and automated computer systems to control one’s greenhouse with the contact of a mobile phone or computer critical.
Although he now operates a “fairly basic” setup, Parker hopes to improve his devices to the stage exactly where he can control every thing remotely, even though he has a range of crops.
“We have planted eggplants, lettuce, chillies, and okra, and so far, everything has developed effectively the end intention is to faucet into the export industry,” Parker explained.
“It is a tough procedure this is something new to Zimbabwe this has turned into a pilot undertaking. As soon as we are all set, we will invite traders to the discipline times and see if any individual is willing to section ways with a decent amount of money of revenue into the procedure,” he added.
Parker materials the nearby current market in Marondera and bordering communities with his develop. He also hopes to recruit a lot more men and women into aquaponics.
